Pelatihan Corona and Partial Discharge

Pendahuluan Training Corona and Partial Discharge

Partial  Discharge  (PD),  as its name would suggest, is an electrical

discharge  that  occurs across a portion of the insulation between two

conducting electrodes, without completely bridging the gap. PD’s are

caused when there is a discontinuity in the insulation system and as a

general  ‘rule-of-thumb’  PD  will  occur  in systems operating at

voltages  of  3000V and above (although it should be noted that PD can

occur at lower voltages than this).

Partial  discharges  can  occur  in  voids in solid insulation (paper,

polymer  etc),  along  the  interfaces of multi-layer solid insulation

systems, in gas bubbles in liquid insulation or around an electrode in

a  gas  (corona  discharge).  Partial  Discharge activity can initiate

under  normal  working  conditions in high voltage equipment where the

insulation   condition  has  deteriorated  with  age,  has  been  aged

prematurely by thermal or electrical over-stressing or due to improper

installation (this leads to ‘infant mortality’).

PD  can  often be observed with the commissioning of new equipment due

to improper installation, poor design and/or workmanship (this is seen

particularly  in  cable  joints  and terminations which are made-up on

site).  It  is  known  that  poor  workmanship  can  lead to ‘infant

mortality’  of  MV/HV networks with a disproportionate percentage of

insulation  failures  being  observed  within  the  first 1-3 years of

service compared to the rest of the service life of the cables/plant.


  1. To understand the basics of stator winding insulation systems and

why they deteriorate

  1. To understand basic Corona and Partial Discharge theory
  2. To understand how Partial Discharge detection devices work
  3. To interpret  the  test  data  collected  and  relate the data to

specific failure mechanisms, to enable you to plan maintenance
