Product Description
- 产品描述
-
Voltage transformer, abbreviated as PT, is an instrument similar to a transformer used to convert voltage. But the purpose of transformer voltage conversion is to facilitate the transmission of electrical energy, so the capacity is large, usually calculated in kilovolt ampere or megavolt ampere units; The purpose of voltage transformers in converting voltage is mainly to supply power to measuring instruments and relay protection devices, to measure the voltage, power, and electrical energy of lines, or to protect valuable equipment, motors, and transformers in the event of line faults. 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. The entry introduces its basic structure, working principle, main types, wiring methods, precautions, exceptions and handling, as well as ferromagnetic resonance.
