108HMK4 in stock German 108HMK4 electrical components 108HMK4 inventory

108HMK4 electrical components are instruments used to transform voltage. However, the purpose of a transformer's voltage transformation is to facilitate power transmission, so its capacity is large, generally calculated in kilovolt-amperes or megavolt-amperes; whereas the purpose of a voltage transformer's voltage transformation is mainly to supply power to measuring instruments and relay protection devices, to measure line voltage, power, and energy, 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, with a maximum not exceeding one
