METALISNEJDEK electrical components Germany METALISNEJDEK model METALISNEJDEK price

METALISNEJDEK electrical components are instruments used to transform voltage. However, the purpose of a transformer in transforming voltage is to facilitate the transmission of electrical energy, so its capacity is large, generally calculated in kilovolt-amperes or megavolt-amperes; whereas the purpose of a voltage transformer in transforming voltage is mainly to supply power to measuring instruments and relay protection devices, to measure the voltage, power, and electrical energy of the line, or to protect valuable equipment, motors, and transformers in the line when a fault occurs. Therefore, the capacity of a voltage transformer is very small, generally only a few volt-amperes or tens of volt-amperes, at most
