Insulation Relay HRI-R40 insulation's resistance monitoring is carried out applying a measure's signalling between isolated network and earth . reducing problems caused by the presence of direct-current components on network (rectifiers). This relay could set a large number of programming possibilities with frontal button and 3 digit digital display for visualising measuring and programming parameters. HRI-R4OW version has same fundamental characteristics of previous model but it uses particular measuring technique , Actually presence in network of strong distortions with high harmonic . Borna niroo karan company(Brnika) is the representative of Contrel on buying , selling, consulting services for automation systems and protective relays including Insulation Relay HRI-R40.
