Voltage transformer divided by voltage conversion principle: electromagnetic voltage transformer: according to the principle of electromagnetic induction voltage conversion Which Zhuhai high voltage transformers, completely similar principle and basic structure and transformers, multi-country adoption in voltage level and below; capacitor voltage Transformer: the capacitive divider, compensating reactor, intermediate transformers, dampers and the carrier device high voltage transformer protection gap and other components used in the neutral grounding system for voltage measurement, power measurement, relay protection and carrier communication use; photoelectric voltage transformer: by photoelectric conversion principle in order to achieve high voltage transformer voltage conversion Foshan Which is good, is still under development. Voltage transformer (PT) and current transformer (CT) is important electrical power system equipment, which bears the isolation between the high volume and high pressure, low pressure system to the low amount of conversion functions. The wiring is correct or not, the normal work protection, measurement, monitoring systems and other equipment has an extremely important significance. When newly installed PT, CT commissioning or replace PT, CT secondary cable, the polarity test method test PT, CT wiring correctness has been essential protection staff working procedures. Which Huizhou high voltage transformer | Huayi Electric Power (certified) | high voltage transformer provided by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
