NEUTRAL POLE LOCATION INDEPENDENT EARTH LEAKAGE DETECTION CIRCUIT

摘要

A neutral pole location independent power supply circuit includes: a first leg including a first diode and a second diode, the first leg is configured for electrical connection to a first phase of the power distribution circuit at a point between the first diode and the second diode; a second leg including a third diode and a fourth diode, the second leg is configured for electrical connection to a second phase of the power distribution circuit at a point between the third diode and the fourth diode; a third leg including a fifth diode and a sixth diode, the third leg is configured for electrical connection to a third phase of the power distribution circuit at a point between the fifth diode and the sixth diode; a fourth leg including a seventh diode and an eighth diode, the fourth leg is configured for electrical connection to a neutral line of the power distribution circuit at a point between the seventh diode and the eighth diode.
