High Voltage Test Equipment
HV HIPOT manufacturers different kinds of high voltage test equipment.
We are One-stop solution supplier for all high-voltage withstand test products based on your requirement.
1. GDYD series AC/DC Hipot Test Set
Power frequency withstand testing is the effective and direct way to test insulation strength for electrical equipment, apparatus, or machines. It checks dangerous flaws which assure electrical equipment continuous working.
AC/DC Hipot Test Set, also called AC/DC dielectric test equipment, can test many types of test object, including:
• Circuit breakers
• Switchgears
• Reclosures
• Wires
• Capacitors
• CT/PT
• Aerial motors platforms
• Hot stick bucket bricks
• Vacuum bottles
• Rubber gloves and boots
• Insulation blankets, ropes
• Many other MV and HV loads
Standard models are available from 10kV-300kV AC.
The control unit has three types for selection,
• GDYD-M series Pointer display controller
• GDYD-D series Digital display controller
• GDYD-A series Automatic PLC controller
2. AC Resonant Test System
AC resonant testing uses resonance way to make withstand voltage testing. It is designed specially for large capacity and high voltage objects, including:
• Power cables
• Power transformers
• Firepower and hydroelectric generator
• GIS
• Bus bar
• CVT
For capacitive test objects such as power cable, GIS, transformers etc., we usually use variable frequency test method, GDTF series AC Resonant Test System.
For inductive test objects such as motors, generators, CVT etc., we usually use inductance adjustment test method, GDTL series AC Resonant Test System.
3. GDYT series Partial Discharge Test System
Some models are corona free, designed to serve as AC sources for partial discharge and power factor/tan delta testing. The system can be designed based on different test objects, by using power frequency method or resonant test method.
4. GIT series SF6 Gas Insulated Mobile High Voltage Partial Discharge Test System
It is specially designed for High voltage GIS, GIS transformers.
It can make below test:
• Power frequency or variable frequency withstand voltage test
• Partial discharge test
• GIS transformer accuracy test
Advantages:
• The high voltage obtained are well sealed and shielded in containers, protect the safety of person, no outside interference.
• Accurate test measurement.
• The safest type of high voltage test.
• If making HV bushing type, hydraulic device is supplied for easy lifting.
• True corona free system.
5. VLF AC Hipot Test Set
VLF AC Hipot Test Set is better used for cable withstanding voltage test.
6. GDZG series DC Hipot Test Set
GDZG series of DC Hipot Test Set is used for testing DC high voltage for zinc oxide arresters, magnetic blowing arresters, power cables, generators, transformers, circuit breakers and other equipment. Rated voltage is 30-500kV.
