 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 causing unbalanced currents in three phase systems. Circular through core current transformer is mainly used in cable circuit environment, which has simple structure, small volume and flexible application. According to the specifications of the cable used in the main circuit, there are many kinds of hole diameters corresponding to the core penetration. The drilled hole diameter of this series of products is from 25mm to 200mm, and the main circuit current 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 new strict 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 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 meets the requirements of lEC61869-2 (2012). Product features Core drilling structure, flame retardant epoxy resin casting, good stability. High magnetic conductivity or nanocrystalline nickel steel, good linearity and high sensitivity. Excellent balance characteristics and strong anti-electromagnetic interference ability. Scope of application Electrical fire control system, fire and leakage prevention,
