Catalog: Circuit Breaker Test Equipments

In order to meet the safety needs of electricity, it is necessary to test the functional characteristics of the circuit breaker. According to the test category, it can be divided into: 1. Characteristics test of circuit breaker  2. Contact Resistance Tester  3. HV hipot  test 4. Insulation resistance test 5. Vacuum test.Below are our recommendation:

1. Characteristics test of circuit breaker 

HVKC-8 Circuit Breaker Analyzer （HV Switch Tester）

It is intelligent, multi-function, data accurate, strong anti-interference, simple operation, small size, light weight, beautiful appearance, etc. It applies to a variety of indoor, outdoor dynamic characteristics test for less oil, more oil switches, vacuum switches, and SF6 switches. The biggest difference in this high-voltage switch dynamic characteristics tester that can be configured universal speed sensor (accelerometer).

2. Contact Resistance Tester 

HVHL Contact Resistance Tester

Test current of the Tester is DC 100A and 200A（600A available）. The tester can measure the loop resistance at this value and display the result in digital and with function of storage, printing and time setting. Another 50A and 150A are optional. It is high precision and good stability and can meet most power systems’ requirements in onsite high-voltage switches maintenance and high-voltage switches factory loop resistance measurement.

5. Vacuum test.

HVZK-IV Vacuum Interrupter Test Set

Without removing, direct quantitative measuring vacuum degree of vacuum switch interrupter. With the quantitative measurement means can not only measure the degree of vacuum of vacuum switch whether is within the normal range, more importantly, for some vacuum switches which leak faster, compared with the measuring results of past years, its life can generally be inferred, prevent accidents. This product is compact, lightweight and compact models, short test time, reliable measurement results, good stability, high precision, fully functional, is the ideal instrument for quantitative measuring vacuum switches.
