온도변화가 보호계전기 동작특성에 미치는 영향

Characteristics Change of Protective Relay in accordance with Temperature

Electro mechanical type protective relay have an influence on the characteristics of the operation due to the change of coil impedance in accordance with the change of the temperature. We found out through an electrical test how many characteric changes are made when we change the temperature according to the types of protective relay. The result is that the protective relay operated by vactor is influenced by temperature.
