3. Problem Statement
• Partial discharge is the dissipation of energy caused by
the buildup of localized electric field intensity.
• In high voltage devices such as transformers; this
buildup charge and its release can be symptomatic of
problems associated with aging such as floating
components and insulation breakdown.
• This is why PD detection is used in power systems to
monitor the state of health of high voltage transformers.

4. Problem Statement
• If such problems are not detected and repaired, the strength
and frequency of PDs increases and eventually leads to the
catastrophic failure of transformer, which can cause
equipment damage, fires and loss of revenue due to
unscheduled outage.
• Reliable PD detection is a critical need for power companies
to improve personnel safety and decrease the potential for
loss of service.

5. Proposed Solution
• PD phenomenon is manifested in a variety of
physically observable signals including electrical and
acoustic pulses and is currently detected using a host of
exterior measurement techniques.
• These techniques include electrical lead tapping and
piezoelectric transducer (PZT) based acoustic
detection. Many modern systems use a combination of
these techniques because electrical detection is an older
and proven technology.

6. Proposed Solution
• Acoustic Signal is created because when the current streamer
is formed within the void, the material around the hot
streamer is vaporized.
• This vaporization causes an explosion of mechanical energy,
which then propagates through the transformer tank in the
form of a pressure field.
• This phenomenon is analogous to the formation of thunder
after a lightning strike.

7. Proposed Solution
• Acoustic detection allows for the source to be located when
several sensors are mounted to the exterior of the tank.
• However, if an acoustic sensor could be placed inside the
tank, acoustic detection be easier due to the increased signal
amplitude and elimination of multipath interference.
• In this project, acoustic detection is used to observe PD
signals.

• Worked on the partial discharge equipment present in
the ‘High Voltage Lab’ in order to bring it in working
condition.
• Tested each component electrically.
• Located the fault or missing component in it.

11. Applications
• Reliably assesses insulation quality throughout
development and operation of high voltage equipment
like:
• Power Transformers and bushings
• Cables, splices and terminations
• Switch gears
• Motors and Generators

12. What we have done so far?:
• Done simulations of the equivalent circuit for PD’s
measurement on Simulink.
• Calculated the circuit parameters and observed their
affect on PD pulses.

13. Observed PD Patterns:
• At the applied voltage of
5 kV PDs are found due
to presence of void
inside the solid
insulation.
• With the applied voltage
of 5kV the field intensity
within the void exceeds
the breakdown strength
of gas in void and PD
pulse is observed which
is shown in Fig. Undergraduate Final Year Project Presentation

14. Hardware Developed
• Done with the transformer tank design
• Have designed the test object to generate PD’s
• Calculated the parameters of Acoustic emission sensors

15. Future Deliverables
• This study will ensure the power engineers to predict
the quality of the insulation used for high voltage
power equipment.
• The present work is to be extended for further study in
different high voltage power equipment such as current
transformer (CT), potential transformer (PT), switch
gear and circuit breaker.
