Circuit breakers are circuit elements used to interrupt and carry current, and to hold current for a certain period of time in abnormal situations such as short circuits. The maintenance and testing of circuit breakers is crucial to ensure operational safety and continuity. They should be periodically maintained and tested once a year.

If circuit breakers are not properly maintained, they can cause significant damage to transformers when opening or closing under high voltage. Secondary protection relays detect malfunction signals and deactivate circuit breakers to prevent them from being damaged.

At Vplus, we strive to ensure operational safety and continuity by guaranteeing that circuit breakers are properly tested and maintained. Our experienced and expert team takes pride in providing you with the best service possible.

Circuit breaker testing is conducted as follows:

• Measurement of opening time of the circuit breaker
• Measurement of closing time of the circuit breaker
• Measurement of the insulation resistance of the circuit breaker
• Measurement of the contact resistance of the circuit breaker
• These processes allow us to identify any issues with the circuit breaker and ensure that it is functioning properly.

Circuit breaker maintenance includes the following:

• Control of the circuit breaker control system
• Inspection of the motor, opening and closing coils
• Oil change for oil circuit breakers
• Mechanical checks of the circuit breaker
• Our experienced and expert team tests and maintains your circuit breakers on-site and delivers them to you in a trouble-free manner. For more detailed information, please feel free to contact us. We would also be delighted to welcome you to our offices located on both sides of Istanbul.
