Current Transformers are generally used in the maintenance process of high-current lines. After applying current sensor, the ultra-high current can be converted into a low voltage that is not harmful to us, so that we can carry out safety measurements. The key role of curent transformer is to reduce the large current of the current…
The current transformer is an instrument that accurately converts a large amount of current on the primary side into a small amount of current on the secondary side according to the magnetic effect of the current. The current transformer is composed of a closed iron core and windings. The number of primary winding turns is…
The general current transformer can convert the primary current with a large value to a secondary current with a smaller value according to a certain transformation ratio, so that it can be used for maintenance and accurate measurement. The main function of the zero-sequence current transformer is to protect the operation and disconnect the switching…
Most technicians are very familiar with the GFCI sensor for ground fault current detection.The detection principle is as follows: In a three-phase system, a chip-type RCMU (leakage current monitoring unit) is placed on the bus. The most important thing is that all three buses pass through the middle hole of the RCMU randomly. The…
Empowering the Future of Mobility with Safe Charging Solutions The rapid rise in new energy vehicles over the past two years has necessitated an equally robust expansion in charging infrastructure. Ensuring the safety of electricity during charging, particularly in preventing leakage currents that can endanger lives and property, is crucial. Residual Current Devices (RCDs) are…
Understanding the Differences Between Current Transformers and Zero Sequence Current Transformers Current transformers (CTs) and zero sequence current transformers (ZSCTs) are essential components in electrical systems, playing critical roles in protection and measurement. Understanding the differences between these two types of transformers is crucial for engineers and technicians working in electrical safety and system design.…
