Types of Partial Discharge
4 Types of Partial Discharge:
❑ Internal Discharge
- Occurs within a void in insulation such as gaps in solid
or gas bubbles in oil
❑ Surface discharge
- Occur when there is a degradation of the surface of
the insulator caused by contamination
- Electrical Treeing
• Insulator contains a carbon-based compound →
carbonization and form carbon track on surface
❑ Arcing
- An electric arc, or arc discharge, is an electrical
breakdown of a gas that produces a
prolonged electrical discharge or plasma discharge
❑ Corona
- Occurs when the air surrounding a conductor is
ionized, causing an electrical discharge.
- Discharge to air

Importance of Grounding
28
•
Good grounding not only for safety, its also prevent damage to industrial
plants and equipment.
•
Good grounding system will improve the reliability of equipment and reduce
the damage due to lightning or fault current .
•
To provide a safe path for the dissipation of fault currents, lightning strikes,
static discharges, EMI and RFI signals and interference.
•
National Fire Protection Association (NFPA ) and IEEE have recommended a
ground resistance value should be 5ohm or less

Standards – EN50160
What is EN50160?
• The EN50160 standard is used across Europe to describe the allowable levels of power quality provided by electricity
distributors, it includes a range of measured variables and the allowable level for each individual measured parameter,
these include:
– Frequency
– Short interruptions
– Long interruptions
– Flicker PST
– Flicker PLT
– Interharmonic voltage
– Temporary overvoltages
– Voltage dips
– Voltage variations
– Harmonic voltages
– Mains signaling voltage
– Rapid voltage change
– Voltage unbalance
The power quality is measured at the point where the
utility transfers power to the consumer, at the point of
common coupling (PCC), where the utilities revenue meter
is typically located.
The EN50160 has some serious limitations, it includes a
significant amount of time during the any seven days
period when power quality does not have to meet the
allowed level for many hours per week.
The described levels are useful for all users as a basic
description of the power quality state of health.
Applies to HV, MV and LV networks with different
allowable levels at each voltage
EN50160 is used more as the starting point of negotiation with the power utility and
consumer rather than a minimum quality standard the utility agrees to.
41
41
Standards – IEEE519
What is IEEE519-2014?
• The IEEE519 relates to the distortion requirements when installing harmonic loads on the power network.
• The standard details the allowable voltage and current distortion limits allowable at the point of common
coupling
• Different voltage distortion limits apply at separate voltage levels of:
1kV, 1kV to 69kV, 69kV to 161kV and over 161kV:
• The current distortion limits apply at a different set of voltage levels:
120V to 69kV, 69kV to 161kV and over 161kV
• During testing the load is operated to discover the level of distortion created during typical operating cycles.
Harmonic loads within this context are non-linear loads such as static power converters, arc discharge devices, saturated magnetic
devices, and, to a lesser degree, rotating machines. Nonlinear loads change the sinusoidal nature of the ac power current (and
consequently the ac voltage drop), thereby resulting in the flow of harmonic currents in the ac power system that can cause
interference with communication circuits and other types of equipment.

IEC61000-4-7 - Harmonics
• The IEC61000-4-7 standard is a general guide on harmonics and interharmonic measurement and
instrumentation for power networks
• It describes in detail the methods that should be used for measurement and classification of the measured
values of harmonics and interharmonics
• In addition to the main standard there are two additional annex documents that describe the measurement
of interharmonics and harmonics in the frequency range above 9kHz.
• These two documents are informative, that is that are not strictly part of the standard.
• The standard does include a variety of limits that other standards specify in a number of examples to show
how the standard is used but nominally does not have built-in limits. These standards include:
• IEC 60038
• IEC 61000-2-2
• IEC 61000-3-12
• IEC 61000-3 series (various standards)
The purpose of this standard is to ensure that measurements of harmonics are consistent by various
measurement instrument so that results can easily be compared when multiple instruments are
used.

IEC61000-4-15 / IEEE1453 Flicker
• The IEC61000-4-15 and IEEE1453 describe the methods of measurement of flicker in power systems.
• Flicker is caused by fluctuations in the power system voltage which result in observable changes in the light output
of electric lamps. It can be an annoyance and hindrance to workplace productivity and visually affect susceptible
individuals.
• The fluctuation may also cause detrimental effects to electrical equipment such as nuisance tripping of breakers,
unwanted switchover in UPS systems and problems with sensitive electronic equipment that need constant
voltage (e.g. medical equipment)
• The basic measurement of flicker is PST, short term flicker and PLT, long term flicker. Short term is considered over a
10 minute period and long term over a 2 hour period.
• A PST value of 1.0 for flicker represents a figure that 50% of people would perceive flicker in a 60W incandescent
bulb. Although incandescent bulbs are used less frequently the overall effect of flicker remains present on other
lighting and equipment.
• The two standards are almost identical, the IEC standard refers to 230V operated system and the IEEE refers to
120V operated systems.
The typical source of voltage flicker comes from randomly operating loads such as arc furnaces,
welding machines, intermittently starting and stopping induction motors.
45
45
IEC61000-4-30
• The IEC61000-4-30 standard describes the measurement and testing methods to be used by power quality
measurement instruments. It allows two classes of instruments, Class A and Class S.
• Class A offers the best accuracy and Class S is considered to be acceptable for regular power quality surveys.
• The main differences in accuracy are in the measurement of voltage and time. For Class A, voltage accuracy of 0.1
% of declared input voltage UDIN over the range of 10% to 150% of UDIN is required
• For time accuracy, ± 20 ms for 50 Hz and ± 16.7 ms for 60 Hz is required regardless of the total time interval.
Achieving this accuracy requires either a GPS clock via a GPS receiver or NTP (Network Time Protocol) via Ethernet
• The standard describes the method required for measurement (as per IEC61000-4-7 and -15) and dictates the
methods used for classification and flagging of specific items to enable consistent reporting.
• The Fluke 1740 series will be independently verified to comply with Class A by an external agency.
Class A is particularly useful in dispute resolution between the power supplier and the consumer,
the higher accuracy requirements for Class A analyzers enables both user in the dispute to make
measurements that will be identical.
46
46
23
2/22/2021
Class A Data
Aggregation:
• Data is specified to aggregate at multiple rates depending upon the logged value. The primary aggregation periods
are:
• 150/180 cycles (150 cycles for 50Hz and 180 cycles for 60Hz)
• 10-minute interval
• 2-hour interval (note that the 10 minute and 2-hour periods are those specified for flicker in IEC61000-4-15)
• The 10-minute interval is the one which most data is represented by, each 10-minute interval is made up multiple
150/180 cycle periods
Event Capture
• The identification of the time stamp of events (any significant change in the voltage) is made based on the
occurrence of the event with a half-cycle trigger – that is a half cycle RMS voltage outside of limit will be classified as
an event.
• To identify the occurrence of an event each part of the event is ‘flagged’ to indicate that item is part of one event –
this is to ensure that the effects of the event are consolidated into one for simplicity of analysis.
47
47
Measurement Standard Summary
• The prevailing standard for power quality can be split into two areas:
• Measurement and evaluation (for equipment)
• IEC61000-4-7 (Harmonics)
• IEC61000-4-15 (Flicker)
• IEC61000-4-30 (Methods)
• Evaluation of logged data against limits
• EN50160
• IEEE519
• GOST (Russian standard)
• This is not a comprehensive list of standards for power quality, but these are most frequently quoted standards.
• In many cases there a geographical adaptation of the standards which evaluate against limits which use locally
defined limits, the Fluke 1740 series have adjustable limits to adapt the instrument and reporting to these
situations.
• There are also localized reporting standards that can be configured within the instrument and in reports in the
application software.
The purpose of any standard is to ensure that repeatable results are being created every time,
whether that be in the measurement and evaluation of data or whether that is in the evaluation of
data against allowable limits.

What are the harmonics ?
• In a normal ac power system, voltage
varies sinusoidal
• With non-linear loads such a rectifiers
and switches, the current draw is not
necessarily sinusoidal
• The waveform is then complex
• The complex waveform can
be decomposed into individual
sinusoidal components
• These harmonic components impact
motors, transformers, cabling and other
electrical components
49
Identifying harmonics waste
Power quality analyzers display a spectrum graph of harmonic components present in a system, but the graph on its own
does not quantify the amount of energy wasted by harmonics.
Harmonics cause:
• unusable power, drawn from utility but not
converted to actual work
• high current to flow in neutral conductors
• motors and transformers to run hot, decreasing
efficiency and shortening lifespan
• increased susceptibility to voltage sags
• reduced transformer efficiency — or, a larger
unit is required to accommodate harmonics.

and death for any number of patients who are reliant on its systems functioning at
optimum levels.
• Batteries operate by converting chemical energy into electrical energy
through electrochemical discharge reactions.
• Batteries are composed of one or more cells, each containing a
positive electrode, negative electrode, separator, and electrolyte
• Batteries are rated in terms of their nominal voltage and ampere-hour

• Most battery manufacturers specify <0.5% AC ripple voltage of
the DC voltage
• High ripple voltage will produce
ripple current battery temperature
and resulting energy loss
• Temperature conversion rate
is about: 4.6 W/m²/ °C
• Damage to the battery life of battery
temperature increases
• High ripple voltage may be due poor quality or poorly performing
charging equipment
• Up to 20 ripple voltage readings can be saved in one profile .
