WebSep 1, 2024 · To detect that state change, basically 2 methods are usually used: Voltage divider method; Measures voltage change. Resistance threshold method; Measures resistance change. These methods are not applicable when both sides of the circuit breaker are grounded, because the signal change is not detectable. Alternative test … WebThis test is conducted by injecting DC current through the breaker main contact system when the circuit breaker is closed, and measuring the voltage drop so that the resistance can be calculated. The resistance reflects the condition of the conducting parts.
