Product Description

Circuit Breaker Analyzer Dynamic Characteristic Analyzer

The Circuit Breaker Analyzer serves as an essential tool for the inspection and analysis of parameters associated with AC high-voltage switches, including AC high-voltage circuit breakers, load switches, and isolating switches. It is capable of comprehensively measuring and evaluating all mechanical characteristic parameters of circuit breakers, with an innovative testing approach that assesses the wear of arc-extinguishing contacts. This device is widely applied in the detection and analysis of parameters for various AC high-voltage switching devices, ensuring their operational integrity and safety.

Type Tests of Circuit Breaker

Type tests are organised with the aim of proving the abilities and making sure the rated characteristic of the circuit breaker are exact. Such tests are conducted in the specially built testing laboratory.

1. Mechanical Test- It is mechanical ability type test involving the repeated opening and closing of the breaker. A circuit breaker must close and open at proper speed and do its allocated job and function without any failure.
2. Thermal Test- Thermal tests are carried out to check the thermal behavior of the circuit breakers. Due to the streaming of rated current through its pole in a rated condition, the breaker under test undergoes steady-state temperature rises. The temperature rise for rated current should not exceed 40° for current less than 800A normal current and 50° for normal value of current 800A and above.
3. Dielectric Test- These tests are performed to check power frequency and impulse voltage withstand capacity. Power frequency tests are kept on a new circuit breaker; the test voltage changes with a circuit breaker rated voltage. In impulse tests, impulse voltage of particular value is employed to the breaker. For outdoor circuit dry and wet tests are conducted.
4. Short -Circuit Test- Circuit breakers are subjected to sudden short-circuits in short-circuit test laboratories, and oscillograms are taken to know the behaviour of the circuit breakers at the time of switching in, during contact breaking and after the arc extinction. The oscillograms are studied with particular reference to the making and breaking currents, both symmetrical and asymmetrical restriking voltages, and switchgear is sometimes tested at rated conditions.
