互感器是电力系统中测量仪表、继电保护等二次设备获取电气一次回路信息的传

Transformer is a sensor that obtains information of electrical primary circuit by measuring instruments, relay protection and other secondary equipment in power system. Transformer turns high voltage and large current into low voltage (100, 100 /) and small current (5, 1A) in proportion. The primary side is connected to the primary system, and the secondary side is connected to the measuring instrument and relay protection. <br>In order to ensure the safety of the staff when they touch the measuring instrument and the relay, each secondary winding of the transformer must have a reliable grounding to prevent the insulation between the windings from being damaged and the secondary part to have high voltage for a long time. <br>Transformers include two major categories of current transformers and voltage transformers, mainly electromagnetic.

The transformer is a sensor in the power system for obtaining electrical once-in-a-loop information from secondary equipment such as measuring instrument and relay protection. The transformer converts high voltage, high current proportionally into low voltage (100, 100/) and small current (5, 1A), which is side-by-side in a system, secondary side-on measuring instrument and relay protection, etc. <br>In order to ensure the safety of the staff when touching the measuring instrument and relay, each secondary winding of the transformer must have a reliable ground to prevent damage to the insulation between windings and the long-term high voltage of the secondary part. <br>Transformers include current transformers and voltage transformers, mainly electromagnetic.
