Transformers (instrument transformer), also known as instrument transformers, current transformers and voltage transformers are collectively. High voltage can become a low voltage, high current into a small current transformer for measuring or protective system. Its main function is to high voltage or high current in proportion converted into standard low voltage (100V) or standard low-current (5A or 1A, refer to the rating), in order to realize the measurement instruments, standardized equipment protection and automatic control equipment, small technology. At the same time the high voltage transformer can be used to separate high voltage transformer system Hanzhong, in order to ensure the safety of persons and equipment. In order to transmit electricity power system, often using AC voltage, high current loop power sent to the user, can not be directly measured with instruments. Transformers and measurement instruments and measurement devices with high voltage transformers in Yulin, one can measure voltage, current and power systems; and relay protection and automatic device fit on the grid can be constructed of various electrical fault protection and automatic control. Transformer performance will directly affect the accuracy and reliability of relay protective devices power system measurements, measure.
