Current Transformer - Multi-secondary Winding Design, Overvoltage Protection Features

According to the needs and demands of our clients, we are engaged in supplying and trading of Current Transformer in Ahmedabad, Gujarat, India. Current transformers can be regarded as transformers working in short-circuit, with the full normal current flowing through their primary side. Devices connected on the secondary side are series-connected. Current transformers can have several secondary windings with magnetically separated cores of the same or different characteristics. They can, for example, be equipped with two measuring cores of different accuracy class, or with measuring and protection cores with different accuracy limit factors. Due to the risk of overvoltages, current transformers must not be operated with open secondary terminals, but only in short circuit or with the burden of the measuring equipment.
