Product overview

Partial discharge detection system specifically for transformers, motors, transformers, cabling, GIS, switch, surge arresters, measurement of partial discharge in electrical equipment. Its technical can fully conform to IEC-270 standards and GB7354 standards, electrical equipment manufacturing, supply operations, installation and commissioning of electric power construction sector the necessary test equipment.

Working principle

Local discharge detection system principle: try products produced once local discharge Shi, try products Cx ends produced instantaneous of voltage changes δ u, after a coupled capacitor Ck coupled to detection impedance Zm, loop in the will produced a pulse current I, will this pulse current I by detection impedance Zm produced of pulse voltage for sampling, zoom and displayed processing, on can determination local discharge of depending on in discharge volume, parameter. Impulse current method using partial discharge signals than low-frequency part of the spectrum to avoid radio interference.
Partial discharge detection system configuration-RLC measuring impedance measurement of partial discharge pulse signals and inhibit the power frequency and other low-frequency interference signals.
Partial discharge detection system pulse peak direction testing system, with computer program-controlled filtering, amplification, sampling, storage and display functions. Data acquisition synchronized with test voltage. Using the direct method, method of bridge balance, repetition rate n, average discharge current I, d squared rate, can be used for a variety of maps: q-n, q-ф, q-ф-t, partial discharge test system can detect less than 1000pC of partial discharge ultrasonic signal.

Performance characteristics

Partial discharge detection system according to IEC YDJF (270), using pulse current method developed by. The instrument has four high frequency oval scan, type applicable to high-voltage products, factory testing, new product development, motors, transformers, cables, bushings, capacitors, transformers, surge arresters, switch and other high voltage partial discharge test. Available to manufacturers, scientific research departments, used in the electricity sector.
