Protection current transformers

Protection current transformers perform a vital task in electric circuits. They are used to produce a proportional current in their secondary windings and this is then isolated from the main power circuit. The proportionally reduced current is then utilised as the input to protective relays, which in turn isolate a section of the main circuit should it suffer a fault or failure. This technique allows any unaffected portion of the circuit to remain operational. Production current transformers are a core part of SADTEM’s product range, which also features current and voltage transformers for indoor and outdoor use, combination transformers and bushing transformers.
