Grounded voltage transformers with build-in protection device ZNOLPM (ЗНОЛПМ)Grounded voltage transformers with build-in protection device ZNOLPM (ЗНОЛПМ)
The transformers are intended for embedding in factory-assembled switchgears, conductors and are used for powering electrical measuring devises, protection, signaling and control circuits in 50 or 60 Hz networks with insulated neutral . The transformers are manufactured in climatic design version "У" (moderate) and "T" (tropical) according to the standard requirements of GOST 15150 location category 2 with built-in protection unit. Mounting in any position The position of primary winding tapping may be either on a front or back side of transformer (see transformer scheme below). Table 1. Technical data
*) Is intended for usage as second main secondary winding (for powering measuring instruments). Burden of both secondary windings, as well as required accuracy classes should be specified in the order. **)Required burden should be specified in the order.
