The AC Withstand Voltage Test Device is widely used in power system equipment testing, including transformers, switchgear, insulators, bushings, cables, and electrical components. Its intuitive 7-inch touch screen (optional 10-inch), fully digital calibration, and automatic/manual test modes make it suitable for both field and laboratory environments.
With real-time display of voltage, current, and status, as well as intelligent safety reminders and result judgment, the device ensures fast and accurate dielectric strength tests. It is ideal for:
Factory routine testing of high-voltage apparatus
On-site commissioning of substations and power stations
Preventive maintenance in power grid companies
R&D and lab testing in electrical equipment manufacturing
High-voltage insulation performance validation after repairs or overhauls
The system enhances safety and efficiency with voice alarms, flashing high-voltage warnings, password-protected settings, and multi-device compatibility, offering a modern solution for high-voltage withstand testing needs.
The high-voltage circuit breaker running in test system is designed for the running in test of high-voltage circuit breakers. It can simultaneously control the running in test of six circuit breakers. The parameter setting is intuitive, the timing control is simple, and the work efficiency is improved. The control ability of using time relays for running in avoids the disadvantage of burning out the opening and closing coils, effectively protecting the integrity of the circuit breakers. The KDGK-MH high-voltage switch running in test system is easy to operate and is a commonly used tool for circuit breaker design and testing.
This measuring instrument is widely used in the manufacturing plants and operation sites of various high and low voltage switches and switch cabinets.
This measuring instrument is widely used in the manufacturing plants and operation sites of various high and low voltage switches and switch cabinets.
It is suitable for measuring the speed of switches produced by switch factories at home and abroad.
For high and low voltage switchgear manufacturers to produce high and low voltage switchgear before the factory power test.
It provides an independent test power supply for the field operation test of the high voltage switch, avoids direct use of the DC system in the field control box, effectively prevents the possible harm to the on-site DC system, and provides conditions for the safe operation of the field equipment.
The KDGK-VI high-voltage switch running in test system is designed for the running in test of circuit breakers (high-voltage switches) and contactors (only closing coils).
The KDGK-II high and low voltage switchgear power on test bench is used for conducting various power on tests on high and low voltage switchgear before leaving the factory
The KDGK-F circuit breaker dynamic characteristic tester is suitable for mechanical characteristic testing of various models of SF6 switches, GIS composite appliances, vacuum switches, and oil switches.
The KDGK-2016 isolation switch finger pressure tester is used for checking the finger pressure, and changing the shape of the pressure sensor can also measure the finger pressure of the circuit breaker.
The KDZD switchgear power on test bench is used for conducting various power on tests on high and low voltage switchgear before leaving the factory.
The KDGK-II comprehensive testing bench is used by high and low voltage switchgear manufacturers to conduct various power on tests on the produced high and low voltage switchgear before leaving the factory.
The KDZK-A vacuum degree tester is a device for identifying the vacuum degree of a vacuum arc extinguishing chamber.
The KDGK-F circuit breaker mechanical characteristic tester can be used for testing and measuring the mechanical characteristic parameters of high-voltage switches in power systems such as vacuum, sulfur hexafluoride, low oil, and high oil at various volt
