The difference in current and voltage in the power supply line varies from a few amperes to tens of thousands of amperes. In order to facilitate the measurement of the secondary instrument, it needs to be converted into a relatively uniform current. In addition,...

　　Open-close current transformer, everyone is familiar with it. Their main function is to convert high values to low values. Suitable for measuring instruments and relays. Generally, the secondary rated current is 5A. So why should the current transformer be grounded?...

　　 Current transformers with “S” and without S both indicate the accuracy level of the measurement current transformer. Under the conditions of regular use, the error of the transformer is within the limit of the rule of this level. The commonly used...

The through-core current transformer does not have a primary winding in its own structure. The current-carrying (load current) wires from L1 to L2 pass through a round (or other shape) iron core made of silicon steel sheet rolling to serve as a primary winding. The...

　　The opening and closing type transformer is not restricted by whether the cable is laid or not. The installation method is as follows: 　　1. Remove the connecting clamps of the transformers “K1ˊ” and “K2ˊ”. 　　 Note: There is no requirement for...

　　 1. According to the engineering drawings, the wiring is proper, the line number identification on both sides should be clear, and the identification range should meet the requirements. 　　 2. The current and working voltage power supply circuit should be grounded at...
