FAQ
Q: What is the difference between GDPD-316M and other partial discharge testers?
A: GDPD-316M integrates TEV, AE, UHF and HFCT four mainstream partial discharge detection methods into one unit, which can detect partial discharge of all types of power equipment. It also has built-in expert diagnosis system, RFID equipment identification and IoT functions, making it the most comprehensive handheld partial discharge tester on the market.
Q: Which detection method should I use for different equipment?
A:
- Switchgears and ring main units: TEV + non-contact ultrasonic
- GIS equipment: UHF + contact ultrasonic
- Power transformers: UHF + HFCT (grounding wire) + ultrasonic
- High-voltage cables: HFCT (grounding wire) + ultrasonic (terminals)
Q: Does the test require power outage?
A: No. GDPD-316M is a live detection instrument, which can perform partial discharge detection on operating equipment without power outage, greatly reducing the impact on power supply.
