GENERAL INFORMATION
WHAT IS ELECTRICAL PARTIAL DISCHARGE?
They are electrical discharges or sparks that occur due to the gaps in the structure of the insulating material or the problems in its continuity between two conductive electrodes and not being able to form a full bridge. It covers the measurement of partial discharges that occur in electrical equipment, components or systems when tested with alternating voltage or direct voltage up to 400 Hz according to IEC 60270 standard.
WHAT IS THE IMPORTANCE OF ELECTRICAL PART DISCHARGE CONTROL?
According to the research done by IEEE; Most of the faults (80%) occurring in medium voltage and high voltage systems are caused by electrical partial discharges. It is usually seen as pulses of less than 1 microsecond duration. Although the pulses are of very short duration, the energy released during the pulse causes the insulating material surrounding the conductor to deteriorate. If left unchecked, it can cause insulation faults.
Even under normal operating conditions, partial discharge may occur in devices and materials that operate with or transmit high voltages due to deterioration due to aging, thermal or excessive electrical stresses, faulty installations, faulty workmanship or faulty designs. As a result of its progress and growth in the insulation material, it can weaken the insulation sufficiently and cause a short circuit between phases or phase-earth in 3-phase systems.
