1) current transformer secondary side absolutely not open during use. Used in ac electric motor the process of removing instrument or relay, should be prior to secondary side short circuit. When installation, wiring should be reliable, should not be secondary side installation fuse; 2) secondary side must be grounded at one end. Prevent damage of the primary and secondary side insulation, high voltage into the secondary side, endangers one's personal and equipment safety; 3) when wiring should pay attention to polarity. The polarity of the primary electric motor low rpm and secondary side of current transformer terminals, all show that the polarity with letters. 4) primary side concatenated in line, the secondary side of relay or measuring instrument series. PT, voltage motor electric transformer, English spelling Phase voltage Transformers, is the primary side of high voltage meter or relay in proportion into suitable rated voltage of 100 v conversion equipment. The working principle of electromagnetic voltage transformer and transformer are the same. Also known as a TV or YH (old symbols).
