Title: Method for discriminating varister
Inventor: SAKAI SEIJI
IPC: G01R31/26
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To stably detect presence of internal defect without degrading a normal article nor excluding a normal article as a defective article. SOLUTION: Using a pulse generator in a step S1, a large current pulse of 1A or larger which, comprising pulse width of 100 msec or less, has a peak value of 90%, or less, of average breakdown current of a varisier is applied to a varister. In a step S2, a dielectric loss of the varister is measured at frequency about 100 kHz or higher using an LCR meter. Then in a step S3, a measured value is judged whether it is within a pre-set range for judgment reference. If judged within the range, it is judged as a good particle, and if judged beyond the range, it is judged as a defective article comprising internal defect.

IPC: H02H3/347
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to carry out maintenance, inspection and other work safely, by providing a reverse current detecting circuit in a molded case circuit breaker as the main portion of each distribution panel, thereby quickly interrupting the breaker for separating the power source side of the breaker. SOLUTION: A detected current by a current detecting section 33 and a detected voltage by a voltage detecting section 2 are inputted to a reverse current detecting circuit 1, and a reverse current or reverse power flowing through a cable 3 is detected. When a current in the reverse direction is detected, a trip coil 32 is energized and a switching mechanism 31 is opened. As means for detection a current in the reverse direction, a phase detecting circuit may be applied because detected signals from the voltage detecting section 2 and the current detecting section 32 are taken and the phases of both the detected signals are compared each other, and a current direction flowing through a current transformer of the current detecting section 33 is reversed, and this can be judged by the phase detecting circuit.  Also, the detection may be performed by applying generally known principles of electrodynamometer type or induction type wattmeter or watt-hour meter. By doing the above, danger to the workers in the conventional maintenance and inspection work can be completely eliminated, thereby fully assuring the safety in the work.
