■ Product Overview
VSPD - 100 - z handheld partial discharge tester can be used with the transient waves (TEV) sensor, the contact type ultrasonic sensor, a non-contact ultrasonic sensors, wide band current transformer and uhf sensor on-line detection transformer, high voltage switchgear, GIS, cable connectors, such as generator partial discharge situation of high voltage equipment. Easy to carry, fast measurement, strong anti-interference ability, easy to use on site.
■ Functional features
▲ Using transient earth wave (TEV) with ultrasonic sensor detection of high voltage switch cabinet partial discharge size, contact measurement and non-contact measurement (hand-held ultrasonic receiving antenna) combined, qualitative and quantitative.
▲ Use wideband current transformer and contact ultrasonic sensor to detect transformer partial discharge size.
▲ Use contact ultrasonic and UHF sensors to detect GIS partial discharge.
▲ Use broadband current transformer to detect the partial discharge size of cable joint.
▲ For the non-contact ultrasonic sensor through the headset for sound analysis.
▲ Can display single channel discharge waveform and trend diagram, can display double channel discharge waveform.
▲ Data storage and waveform capture capture for high-voltage equipment with discharge, convenient for later analysis and comparison.
▲ Yellow, green and red three warning values and discharge waveform display in the same interface, convenient and intuitive.
