Abstract

Applies to stationary or portable, single-phase or polyphase, aircooled separating transformers, associated or not, having a rated supply voltage not exceeding 1000 V a.c., a rated frequency not exceeding 500 Hz, and a rated output not exceeding: - 1 kVA for single-phase transformers; - 5 kVA for polyphase transformers. Also applies to separating transformers having a rating up to 40 kVA, however such transformers are considered as special transformers and are subjected to an agreement between the purchaser and the supplier.
