Product Description
Product overview:
Zero sequence current transformers, also known as core balance current transformers (CBCT), detect the presence of zero sequence currents during short circuit fault conditions such as the occurrence of a single line to ground fault that causes unbalanced currents in three-phase systems.
The circular through core current transformer is mainly used in the cable circuit environment, which has simple structure, small volume and flexible application. According to the cable specifications used in the main circuit, there are many kinds of hole diameter corresponding to the core penetration. The diameter of the pierce hole of this series of products is from 25mm to 200mm, and the current of the main circuit includes 63a-2000a. The series of products can meet the technical requirements of different precision such as 0.2,0.5 and 1. At the same time, it can also meet the strict new national standard for balance characteristics. The unbalanced current output value can also be better than 30mA, 10mA, 5mA, even 3mA, which greatly reduces the false alarm caused by the interference of the current and magnetic field of the main circuit, and provides sufficient guarantee for the reliability of the equipment. Excellent and advanced production process. This series of products meet the requirements of lEC61869-2(2012).
Product features
Core piercing structure, flame retardant epoxy resin casting, good stability.
High magnetic conductivity nickel steel or nanocrystalline, good linearity and high sensitivity.
Excellent balance characteristics and strong anti-electromagnetic interference ability.
Scope of application
Electrical fire monitoring, fire prevention and leakage system, intelligent power system, small current grounding system,
electromagnetic relay protection, microcomputer protection, intelligent power, environmental protection m
