Suitable for testing partial discharge of high-voltage devices such as electrical motor, mutual inductor, cable, bushing, capacitor, transformer, lightning protector, switch and so on.

Partial discharge means the discharge at some partial position of insulation material which do not form the penertrative breakdown. It includes three kinds of discharge style: interior discharge (within the medium), on-surface discharge (on the medium surface) and corona discharge (on the point of electrode).

Technical parameters:

Capacitance range to be tested from 6pF to 250UF

Elliptical sweep time base:

Frequencies 50, 100, 150, 200, 400Hz

Rotating in 120 degree with 30 degree each

Operation mode is standard extension straight line

Input voltage range at the high frequency time-base ellipsoid is 13 to 275V

Display unit adopting 100x80mm rectangle oscilloscope tube, with brightness control and cocusing control knob.

Power supply: 220V +/-10% industrial frequency
