Protection current transformers are for the control of protecting relays which have the task to separate switched circuits in the event of over current. For a save function of these relays a proportional transfer ratio of the transformer up to a multiple of the nominal current is necessary. the protection transformers are used for overcurrent and earth fault protection in balanced protection systems. DEIF offers 15 different physical sizes of the protection transformers.The housing of the transformers is made of impact-resistant thermoplastic to ensure a highly reliable quality. The terminals of the transformers are protected by a cover. Features : - Primary current: 50 – 2,000 A - Secondary current: 5 or 1 A - Burden: 1.0 - 15 VA - Acc. class/protection class: 5P4 - 5P5 - 5P10 - 10P5 - 10P10 Borna Niroo Karan (Bornika) is the exclusive agent of DEIF in the fields of consultation , sales and distribution of power industry products including Protection current transformer products .
