Current Transformer　

Current transformers play a vital safety role by scaling down high currents to safer levels for measurement. Toroidal current transformers, with their ring-shaped core and secondary winding, not only ensure high accuracy but also feature a compact size, making them ideal for applications where space efficiency is crucial. Custom designs can be tailored to meet specific operational standards and specifications. This prevents electrical instruments from getting damaged due to overload and ensures accurate readings for efficient energy management. Bar-type current transformers feature a straight primary conductor passing through a window in the magnetic core, making them particularly suitable for high-current busbar applications. If you’re in the market for current transformers, you’ve come to the right place!
