Suppose that you need to test a 1.5V, AA-size alkaline battery. You can apply a short circuit and measure current, or you can measure open-circuit voltage, but neither method properly tests the ...

BGE reviews several alternatives for a battery open-circuit monitoring device to protect from a dc supply single point of failure.

DC overpotential test of the circuit breaker’s insulation systems. Insulation resistance testing of the circuit breaker’s control wiring. Contact resistance test to measure the circuit breaker’s ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...
