The HZD1601 Power Frequency AC Withstand Voltage Test Equipment is designed for insulation withstand and dielectric testing of power transformers, switchgear, circuit breakers, bushings, insulators and other electrical equipment.
The system consists of a control unit and high-voltage test transformer, generating power-frequency AC high voltage for withstand testing, and can also be configured as an AC/DC test system when DC testing is required. A wide range of voltage and capacity combinations is available — 5kVA/50kV is one commonly used configuration, not the only specification.

FAQ
Is 5kVA/50kV the only specification?
No. It's a commonly used configuration — the system is available in many other kVA and kV combinations.
Can HZD1601 be used for transformer withstand testing?
Yes. It's designed for high-voltage withstand testing of power transformers and other electrical equipment.
Does it only perform AC testing?
No. The standard AC configuration is for power-frequency AC withstand testing; an AC/DC transformer configuration is available when DC testing is also required.
What information is needed for a quotation?
Test object, required test voltage, capacity if known, AC/DC requirement, power supply and test location.
