    摘要: Systems and methods can be provided for measuring the resistance of high power apparatuses. A device can include a current source connectable to a test object, and the ability for measuring current and/or voltage, wherein the current source is a capacitor. By providing the current source as a capacitor, a light weight device is obtained which can be used essentially continuously without periods of non-use during recharging.

    摘要: Methods, computer program segment and apparatus for analyzing high voltage circuit breakers are provided. The method includes electrically coupling each circuit breaker contact to ground, applying a test voltage across a circuit breaker contact, measuring an output voltage signal that is proportional to a capacitance of the circuit breaker contact, changing a state of the circuit breaker contact pair from at least one of an open position to a closed position and the closed position to the open position, and detecting a step change of the output voltage that corresponds to the change of state of the circuit breaker. A circuit breaker test device is provided. The device includes a test voltage source, a filter circuit, and an output circuit for measuring the circuit breaker contact pair capacitance, wherein the test voltage source and filter circuit are configured to be coupled to the circuit breaker contact pair during testing.
