Deals with all safety aspects such as electrical, thermal and mechanical. Applicable to stationary or portable, single-phase or poly-phase, air-cooled, independent or associated, isolating or safety isolating transformers that have a rated supply voltage of not more than 1000 V a,c,, a rated frequency not more than 500 Hz, a rated output not more than 10 kVA. In order to attenuate mains borne disturbances, perturbation attenuation transformers (PATs) are intended to the supply of office machines and the like and have a mid-point lead out in the output circuit. In addition, double or reinforced insulation between circuits required by the installation rules or by the appliance specification is fulfilled by using this transformer. Fuller information of safety in regards to PATs are given in this scope.
