A number of different types of switchgear are
identified on PCMD diagrams, and their
current state is also indicated. For example:
 Withdrawable CB
 Off-load isolator
 HV Fixed pattern CB
 LV ACB (in Open state)
 (Load break) switch
 Fuse-switch
 Switch-fuse
Note: Normally-open switchgear is
identified using the DNOs’ “lollypop”
convention. This is a customisable item.

All diagrams must have at least one source of infeed:
Mains infeed (usually
from a DNO) is coloured
according to its voltage
(eg: red = 11kV)
The other possible
sources of infeed supply
are Generators and
Batteries.
HV and LV busbars may
be distinguished by their
central colour (if live):
HV busbar
LV busbar
Services & Projects - Chris Hodges – 05/04/2012 - Single-user PCMD training v3.5.333
14
Understanding the diagram - 4
PCMD determines the current electrical state of all circuits from
the state of the switchgear
Circuits that are live are shown
in solid colours according to
their voltage. For example:
 green = 33kV
 yellow = 22kV
 red = 11kV
 blue = 6.6kV
 magenta = 3.3kV
 black = LV (eg: 415V)
 grey = dc
These colours may be changed
if required.

Understanding the diagram - 5
Circuits that are not live are shown using patterned lines. This
allows monochrome printers to be used for diagram prints.
For non-live circuits, five
line patterns are used:
 Isolated
 Faulty
 Dead
 Earthed
 Dead/earthed (earthed
beyond a transformer)
Busbars are infilled with the Live colour, or a pattern if Dead,
Isolated, Earthed or Dead/earthed. They may also be shown as
Faulty.

There are also a few special
purpose line styles:
 Neutral earth
 LV Busbar riser (live)
 LV Busbar riser (dead)
The LV Busbar risers may also shown
as isolated.
…and more switchgear:
 HV Fixed pattern CB with one
disconnector
 Withdrawable LV CB
 Contactor (open)

Electrical equipment is usually
installed in secure areas
(substations).
A substation is shown on the
diagram using a dotted line box that
encloses a group of equipment
items. Each substation must be
assigned a unique name.
PCMD uses the more generic term
‘location’, to cover equipment
groupings such as switchrooms,
switchboards, switchyards, and
compounds.

Understanding the diagram - 8
Individual switchboards
within substations can be
shown by ‘nesting’ one
location within another.
In this example, switchroom
HVAC A contains two
packaged substations (M4
and M5), two UPS units, and
two output LV switchboards

Understanding the diagram - 9
Central to the operation of PCMD is the manual updating of the
state of switchgear (DNOs call this action ‘dressing’). When the
state of a switchgear item is changed, its graphical representation
is updated. The symbols used are very simple: in most cases,
only the safety lock, caution sign, padlock and/or earth symbol
are used, together with the open/closed switchgear state.
For example: a
withdrawable CB may be
shown as follows:
 Closed
 Open
 Busbar shutters isolated
with safety lock and
caution sign
 Isolated, and circuit
earthed with safety lock

The command button line is laid out as follows:
Command buttons are sometimes greyed out. This may be
because:
 The security key licence is not enabled for this facility
 This facility is not available in the current operating mode
 There is nothing that this facility can currently operate upon
In the example above, ‘Undo’ is greyed out because no dressing
operations have been ‘done’.

In many electrical systems, the safe operation of switchgear is
managed using Castell keys. PCMD is able to accurately model the
way that Castell key systems operate.
On this diagram, a Castell key
engraved ‘A’ is locked into the
upper CB,
and the key receptacle for the
same key on the lower CB is
empty.
If the upper CB is opened, the key is released, and may be moved
to the lower CB, which can then be closed. In the above example,
each CB can only be closed if the key is present.

Each PCMD diagram set may contain three types of diagram:
Mimic diagram This is used as a means of recording the current electrical
state of the network that is being modelled. All dressing operations must
only be carried out as a means of recording physical plant changes. The
Mimic diagram is shown with a green background.
Copy diagram PCMD allows a user to make a copy of any diagram (including
Checkpoints and Copies). Each copy must be uniquely named, and is selfcontained: all dressing or editing activities are localised within that copy. The
Mimic diagram and its System Activity log are unaffected in any way. A Copy
diagram is shown with a sand-yellow background.
Checkpoint diagram This type of diagram is used to archive previous
versions of the Mimic diagram. A Checkpoint diagram is shown with a cyan
background, and cannot be dressed. A Checkpoint is automatically created
when the diagram has been edited, as the activities that are recorded in the
preceding System Activity log must be kept with the previous diagram layout,
and a new set of System Activity log entries begun for the revised diagram. If
the log was previously empty, then a Checkpoint will not be taken.

Following diagram editing, it must be validated before it can be
used. When the validation confirms that there are no errors, the
user may then run the diagram (thus replacing the previous version
of the diagram) using the Edit Finished button. This button remains
greyed out if validation errors are present.
If the diagram had dressing entries in its System Activity log before
it was edited, then a Checkpoint is automatically taken when the
edited diagram is run up.
When the Checkpoint is created, the diagram’s System Activity log
is moved to the checkpoint file, along with a frozen image of the
current state of the Mimic diagram prior to the edit.
Immediately following the
checkpoint operation, the
Mimic diagram’s System
Activity log is empty, and is
shown thus.

PCMD is able to model network behaviour. Many of the items on a
PCMD diagram mimic the behaviour of their real counterparts:
 A live cable that is set to the faulty state will cause the next
upstream fault-clearing equipment to trip.
 On a closed ring, the next upstream fault-clearing equipment in
both directions will trip
Tripped equipment alarms are raised and displayed as shown in the
example.

PCMD diagrams can be configured with simple automation
functions. These are available in two ways:
 Devices (such as ‘ASCO’ units) that have integral automation
 Independent automation control units that control several items
For example: The two types of ASCO units (mechanical
and static) each have three-terminal symbols that are
placed on the diagram.
When a loss of supply is detected on its currently
connected infeed, the switch is able to automatically
change to the other infeed.

The Automation button on the menu bar is used to:
 select single-step mode for the automation. This allows the
effect of each step to be inspected. The ‘Dismiss’ button is used
to proceed to the next step
 Enable or disable the automation. This can be useful when you
need to set the diagram to a predefined state without automation
actions being triggered during the intermediate steps. This is
normally only available in SysAdmin mode. While automation is
disabled a warning banner message is displayed on the
Commands popup.
 Enable or disable interlocks. This operates in the same way as
the enable/disable automation and allows normally-forbidden
dressing actions to be carried out.

PCMD diagrams can be configured with Electrical interlocks. A
number of interlock options are available. These include:
 Only one of a pair of switchgear items may be closed
 A switch cannot be operated while a CB is closed
 Only two out of a set of three switchgear items may be closed:
In addition, an interlock truth table can be built that allows the
interlocks between a large set of switches to be modelled

PCMD diagrams can be configured with Network
load computation (‘Metering’).
Two symbols may be placed on diagrams:
 Meter symbols are attached to equipment
terminals. For each Meter symbol, total load
downstream is computed when a loading value is
adjusted, or a switchgear open/close change
occurs. The Meter symbols may also be
configured with a full load rating and warning
%age values. Overload and warning load alarm
conditions are indicated on the Meter symbol click to display details. Thus, a user may quickly
appraise the loading state of the network.
 Load symbols are attached to equipment
terminals. The user may then enter network
loading values for those points. Separate values
may be entered for each phase.

PCMD’s behaviour is tailored using operating modes. A number of
standard Modes are provided: these may be amended, or new
Modes may be created. The standard Modes are:
 Assessment – Used when testing a user’s system operating or
network knowledge
 Asset maintenance – Used by non-authorised personnel to
update asset data only
 Engineer – Primarily intended for the person assigned to
updating PCMD’s diagram or database
 Operator – The main operational users of PCMD
 SysAdmin – Used by the system manager to create new user
accounts and Modes, and for other system management work
 Trainee – Used by a trainee to learn about the network, prior to
being assessed.

The accuracy of PCMD’s diagram and associated data is important
for the safe operation of the electrical network. To assist with the
checking of the diagram, PCMD is able to produce a printed report
that is formatted according to the way that equipment is arranged
on the busbars at each location.
The list of the available
reports is accessed by
selecting the Reports

The Busbar report is especially important as it lists each
switchgear item that is connected to a Busbar, reading from left to
right on the diagram. Thus, the user can stand in front of the
actual switchgear panel and check that the report details match
those of the real switchgear.

One of PCMD’s unique capabilities is its use in Authorised Person
training and assessment.
Trainers: It is straightforward for trainers to set up a number of
network configuration scenarios using the Copy function. These
can then be used to support the explanation of network switching,
isolation, locks and labels, earthing etc.
Trainees: Similarly, trainees can be set exercises where they
experiment with pre-configured scenarios to gain an understanding
of how a particular electrical network operates.
Assessment: When Assessment mode is selected, PCMD’s inhibits
and warnings are disabled, and invalid switching options are
offered; thus students are required to use their own judgement. In
addition, faulty line sections are shown as dead (instead of faulty).
Students can then be asked to use switching to locate faults.
Following an exercise, the Switching Activity log thus contains an
objective assessment of a student’s capability.

To set up PCMD to carry out an assessment, the following steps are
suggested:
 Make a copy of the diagram that is to be used for the assessment.
 Dress the copy diagram to the start state required for the
assessment (usually includes the setting of a line to the faulty state,
thus tripping a CB).
 Make a copy of this amended diagram copy, one for each student
(the students names can be used to name each of the copies)
 Arrange for each student to logon, select assessment mode, and
open ‘their’ copy diagram.
 Each student completes some predefined task on the network.
 When the students have finished, the assessor should open each
student’s diagram copy and print out the System Activity log and
the diagram.

On a multi-page diagram, a few equipment items may usefully
appear on more than one page. This allows the remaining
equipment items (that only exist on one of the pages), to be
electrically interconnected. Linking of pages in this way is unlikely
to be routinely carried out, so it is restricted to being a system
management function.
Equipment items that are to appear on more than one page must
be copied from one page to the other using a ‘cloning’ mechanism.
Cloning is carried out as follows:
 Select the item(s) to be cloned
 Select the Clone button

 Move the cloned items to the
required place.
Note: Any change made to the details of a duplicated item will also
be made to its other instance(s). For an item to be completely
deleted, you must delete every instance of it from the pages where
it appears.

To lay out a new diagram, Schneider uses the following general rules:
 Place all main sources of supply (infeeds and generators) at the
top of the page (bottom for an upside-down diagram)
 From there, work downwards with the least important LV
equipment near the bottom of the page
 Switchgear that are infeeds to busbars or supply interconnections
to adjacent substations should be placed above busbars. Outfeeds
are placed below the busbars.
 HV Switchgear sequence L to R on busbars the same as in real life
 All busbars to be set horizontally
 Where possible, cables that are not interconnectors to be vertical
and with no bends – stretch busbars if necessary to achieve this.
 Do not flip symbols horizontally or vertically
 Ensure that all equipment and cables are aligned with the
background grid

There are no hard and fast rules for constructing a diagram but
the following sequence usually works well:
 Sizing of the page. The basic page size of a diagram is usually
dictated by the length of the major busbars. Thus, to determine
the page size, you should set out the switchgear (usually spaced
at 25 or 30mm) for all of the major busbars on the diagram.
Note that items may be easily
copied on the diagram by:
- hold down the Ctrl key,
- click-and-dragging the item,
- release the Ctrl key.
Laying out the busbars gives a
good indication of the required
final page size. You should use
the Page Setup button to adjust
the page size…

…on the Visio Page Setup form. Note that you must select the
‘Page Size’ tab to allow adjustment of the diagram’s page size.
You can choose a predefined size – a metric size
is good as the diagram will
then fit metric paper, when
printed.
Alternatively, if you plan to
use a wide-screen monitor,
you could use a Custom size
whose aspect ratio makes
best use of the available
display space (870mm x
500mm is a good size)
You can also use a Custom size to specify oversize metric aspect
ratio display sizes such as B0 (1440mm x 1000mm).

 Detailed busbar layout. For major busbars it may be helpful if the
layout on the diagram matches the front view of the physical
switchboard. For example:
Note the switch positioning, empty switchgear frames and busbar spurs

 Validate often. You should try to build up the diagram a bit at a
time. If you make a large number of changes, you are likely
(initially) to make a significant number of mistakes. It can
sometimes be difficult to identify what is causing a particular error.
Note that when validation is complete, errors can be located by
selecting an error line and then press the GoTo button.

 Get the graphical layout sorted out first. The device
manufacturer and type, and the device IDs can be entered later.
 Use the Copy function wherever possible. If you have a number
of substations or switchpanels that are very similar, then create the
largest example, and then use this as a copy master for the rest.
 Try to place all equipment items
within location boxes. This simplifies
the IDs for each item of equipment,
and reduces the amount of text that
needs to appear next to each item.
An LV switchpanel may be displayed
as shown.
In this example this switch’s name is:
SB-1.C.2 because it is placed within
panel C, which is within switchboard
SB-1.

 Set up templates of commonly used groups of equipment. To set
up a template on the Templates page, you should select a group of
items on the main diagram page, Ctrl-drag (which copies) the group
to the Templates tab at the bottom of the page: the displayed page
will then automatically switch to the templates page, and you can
then continue to move and drop the group onto the page:
A form will appear for you to confirm
that you want these items grouped
as a template.
Subsequently, just click and drag
the group to the Diagrams (main
page) tab. PCMD will automatically
make a copy of the group and
transfer it onto the main page. (A
demonstration of this feature is
recommended).
