The phase comparator for medium voltage is used to check phase coincidence in three-phase medium voltage networks at 50 Hz frequency. Phase comparison is achieved by making contact with both conductors one after the other. The determination of phase´s coincidence (not coincidence) is signalized by the three highly illuminative LED.
The phase comparators type 113 are constructed for use in outdoor environment without any limitation (it means even in rain, fog and snow), and for indoor environment in higher humidity areas. The comparators are designed for normal climatic conditions (climatic category normal -25 °C až +55 °C).
