Zero current transformer is a leakage current detection component of line fault. It has only one iron core and secondary winding. When it works, the primary three-core cable is passed through the iron core window of the transformer, and the secondary one is connected to the relay with lead wire, and then the output terminal…
1. Structural features Our split core current sensor has a good design structure, beautiful appearance, and a transparent flip-top design for easy wiring. The case material is made of PC/ PA66 alloy, which has the characteristics of high temperature resistance, high mechanical strength and environmental protection; the iron core is made of oriented cold-rolled silicon…
What is the Rogowski coil? The Rogowski coil is a flexible clip-on hybrid inductor coil that can be easily coiled around a current conductor for measuring. It is capable of measuring large currents of several thousand amperes without expanding the size of the voltage transformer. Rogowski coils are electronic voltage transformers used to measure alternating currents such as…
Electrical debugging is a key content in the work of power installation engineering projects. In the electrical debugging work, the secondary circuit inspection is also a key adjustment content. It is related to the precise measurement, maintenance, communication and other functions of the power supply system. A prerequisite that cannot be fully utilized. In the…
The intelligent motor protector integrates the functions of measurement, control, protection, network communication, etc., and can protect the three-phase asynchronous motor. The modular design of the fully intelligent motor protector, the main controller and the display operation module are separated, according to the actual situation whether to use the display operation module. The product is…
The safe operation and management of transformers is the focus of everyone’s daily work. Based on the experience exchange of abnormal operation conditions and common problems analysis of transformers, it will be helpful to immediately and accurately determine the causes and characteristics of common faults, and take immediate measures to ensure The safe operation of…
