Product Introduction
The MOEORW-WPG15-5kVA/50kV no-partial-discharge withstand voltage test system adopts SF₆ gas insulation and a lightweight structure, with partial discharge ≤5pC. It is specially designed for on-site non-PD withstand voltage and insulation testing. Lighter and pollution-free compared with traditional oil-immersed types, it outputs stable and clean power frequency high voltage, accurately identifies insulation defects, and is ideal for frequent mobile operations and high-precision PD tests.

FAQ
Q: Why SF₆ insulation?
A: SF₆ provides high insulation strength, non flammability, low PD, and lighter weight.
Q: What is the normal operating pressure?
A: 0.2–0.35MPa; recharge below 0.15MPa.
Q: Can it do PD test directly?
A: Yes, with a PD detector, coupling capacitor, and protective resistor.
Q: How long can it run continuously?
A: Max 30 minutes at rated load; cool down 5–10 times the working time.
Q: Can it be used in humid weather?
A: Recommended humidity ≤85%; clean insulation parts with alcohol in rainy seasons.
