Objects that are stopped inside a zone for longer than the defined amount of
time will trigger the rule and raise an alarm.
Dwell detection
Objects that dwell inside a zone for longer than the pre-defined amount of
time will trigger the rule and raise an alarm.
Directional Detection
Objects that travel in the configured direction (within the limits of the
acceptance angle) through a zone or over a line trigger the rule and raise an
alarm.
Tailgating Detection
Object tailgating is defined as two objects crossing a virtual line or zone
within in a pre-defined time frame. For example, a second unauthorized
vehicle enters a parking lot close to a first vehicle that has access
permission, or two people enter a security zone with a single access card.
Object Classification
VCA can perform object classification once the camera has been calibrated.
Object classification is based on properties extracted from the object
including object area and speed.
Objects Counting
Up to 40 counters linked to the detection rules, provide counting of all
detection objects.

MAINTENANCE FREE EARTHING AND BONDING SYSTEM
Scope
This document covers earthing & bonding system to be adopted for signaling equipments
with solid state components which are more susceptible to damage due to surges,
transients and over voltages being encountered in the system due to lightning, sub-station
switching etc. These signalling equipments include Electronic Interlocking, Integrated
Power supply equipment, Digital Axle counter, Data logger etc.
2.
References
IS 3043 : Code of practice for earthing
ANSI/UL 467 : Grounding & bonding equipment
IEEE 80 : IEEE guide for Safety in AC sub-station grounding
IEEE 837 : Standard for qualifying permanent connections used in sub-station grounding
IEC 62305 : Protection against lightning
3.
Importance of Earthing
The installation and maintenance of an effective low resistance earthing system is
essential due to the following –
• Efficiently dissipate heavy fault currents and electrical surges, both in magnitude
and duration, to protect equipment being damaged so as to minimize down time,
service interruption and replacement cost.
• Provide a stable reference for electrical and RF circuits at the installation to
minimize noise during normal operation.
• Protection of personnel who work within the area from dangerous electric shock
caused due to “step potential” or “touch potential”.
4. Characteristics of good Earthing system
•
Excellent electrical conductivity
-
Low resistance and electrical impedance.
Conductors of sufficient dimensions capable of withstanding high fault currents
with no evidence of fusing or mechanical deterioration.
Lower earth resistance ensures that energy is dissipated into the ground in the
safest possible manner.
Lower the earth circuit impedance, the more likely that high frequency lightning
impulses will flow through the ground electrode path, in preference to any other
path.
-
•
High corrosion resistance
The choice of the material for grounding conductors, electrodes and connections
is vital as most of the grounding system will be buried in the earth mass for many
years. Copper is by far the most common material used. In addition to its
inherent high conductivity, copper is usually cathodic with respect to other metals
in association with grounding sites, which means that it is less likely to corrode in
most environments.
•
Mechanically robust and reliable.

of loop earth consisting of more than one earth pit shall be done. The number of
pits required shall be decided based on the resistance achieved for the earth pits
already installed. The procedure mentioned above for one earth pit shall be
repeated for other earth pits.
The distance between two successive earth electrodes shall be min. 3mtrs. and
max. upto twice the length of the earth electrode i.e. 6 mtrs. approx.
These earth pits shall then be inter linked using 25X2 mm. copper tape to form a
loop using exothermic welding technique.
The interconnecting tape shall be buried at depth not less than 500mm below the
ground level. This interconnecting tape shall also be covered with earth
enhancing compound.

in individual rooms shall be termed as Sub equi-potential busbars (SEEB). The equipotential earth busbar located in the IPS /Battery charger room and directly connected
to Class ‘B’ SPDs and the main earth pit shall be termed as Main equi-potential earth
busbar (MEEB).
The EEBs shall have pre-drilled holes of suitable size for termination of bonding
conductors. The EEBs shall be insulated from the building walls. Each EEB shall be
installed on the wall with low voltage insulator spacers of height 60mm. The insulators
used shall have suitable insulating and fire resistant properties for this application. The
EEBs shall be installed at the height of 0.5m from the room floor surface for ease of
installation & maintenance. All terminations on the EEBs shall be by using copper lugs
with spring washers.
