Resistance Switching in Circuit Breaker refers to a method adopted for dampening the over-voltage transients due to current chopping, capacitive current breaking, etc.; In this method, a shunt resistance is connected across the contacts of the circuit breaker. WebThe chopping current depends on the moment of contact separation: the closer the contact opens to current zero, the higher is the chopping current. The statistical nature of the chopping current is incorporated by considering Gaussian distribution with 15% standard deviation from the calculated value of the mean chopping current. raw ginger in tea
