rehau electrical components Germany rehau model rehau price

rehau electrical components are instruments used to transform voltage. However, the purpose of a transformer 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 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 in the line, so the capacity of the voltage transformer is very small, generally only a few volt-amperes or tens of volt-amperes, with a maximum not exceeding one thousand volts
