Title:
零相変流器の平衡特性試験装置
Document Type and Number:
Japanese Patent JP7378644
Kind Code:
B2
Abstract:
Provided is a device for testing the balance characteristics of a zero-phase current transformer, the device being capable of testing the balance characteristics using a current source having a low output. The present invention comprises an electric wire (1) installed so as to penetrate a through-hole in a zero-phase current transformer (100) a plurality of times back and forth, a current source (2) that channels a DC current to the electric wire (1), and an ammeter (3) that measures the magnitude of a secondary current in the zero-phase current transformer (100).
