Description

ARM2 CLASS II ISOLATION TRANSFORMERS The peculiar characteristic of IREM ARM2 Isolation Transformers is their compliance to Standard EN 61558-1, certified by CESVIT-CETACE. Therefore these isolation transformers, being classified as “class II transformers”, allow the building of plants assuring both the safety of operators and the continuity of operation of the connected transmission systems. In other words, it is possible to: install only a thermomagnetic circuit breaker without residual-current protection on the line fitted with double-insulation cables, connecting the “delivery point” to the isolating transformer; install specific surge arresters for protection against atmospheric discharges on the primary winding of the transformer. The non-use of residual-current circuit breakers avoids the untimely circuit opening due to very small leakages caused by inductive phenomena.
