Title:
DEVICE FOR POWER RECEIVING AND DISTRIBUTING FACILITY
Document Type and Number:
Japanese Patent JPH08298720
Kind Code:
A
Abstract:

PURPOSE: To provide a compact device for power receiving and distributing facility with a reduced installation area.

CONSTITUTION: Contacts 27A-27F, for example 27A, for corresponding a numeric value indicated by a timing signal ABC every time the timing signal ABC successively changes, are closed and the other contacts 27B-27F are opened, thus inputting a time-multiplexing signal 16 of the closing contact from a current/voltage switcher 15 and the timing signal ABC to a judgment and hence reducing an auxiliary current transformer and an auxiliary transformer for current, voltage, and power, drastically reducing installation area, and hence reducing the device for power receiving and distributing facility. Also, a distribution line can be treated more easily.
