[0002] Voltage transformers (PT, TV for short) are very similar to transformers, both of which are used to transform the voltage on the line. However, the purpose of transformers to transform voltage is to transmit electrical energy, so the capacity is very large, generally calculated in kilovolt-amperes or megavolt-amperes; while the purpose of voltage transformers to transform voltage is mainly to power 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 line fault occurs. Therefore, the capacity of voltage transformers is very small, generally only a few volt-amperes, tens of volt-amperes, and the maximum does not exceed one thousand volt-amperes.
