Deals with all aspects of safety such as electrical, thermal and mechanical and relates to stationary or portable, single-phase or poly-phase, air-cooled (natural or forced), independent or associated, isolating or safety isolating transformers, having a rated supply voltage not exceeding 1000 V a.c., a rated frequency not exceeding 500 Hz, a rated output not exceeding 10 KVA. Perturbation attenuation transformers are intended to the supply of office machines and the like and have a mid-point lead out in the output circuit in order to attenuate mains borne disturbances.
