Voltage transformer divided by voltage conversion principle: electromagnetic voltage transformer: according to the principle of electromagnetic induction voltage conversion Shenyang high-voltage transformer, completely similar principle and basic structure and transformers, multi-country adoption in voltage level and below; capacitor voltage transformers: by capacitive divider, compensating reactor, intermediate transformers, protective devices and the carrier damper gap, etc., used in the neutral grounding system for voltage measurement, power measurement, relay protection and communication with the carrier; photoelectric voltage transformer control: by photoelectric conversion principle to achieve voltage conversion Chifeng high voltage transformers, is still under development. Voltage transformer divided by the conditions of use: indoor voltage transformers: distribution equipment installed in the indoor high-voltage transformers in Dalian, generally used in voltage level and below; outdoor type voltage transformer: power distribution equipment installed outdoors, the use of at and above voltage level.
