Rotating electrical machines - Standard methods for determining losses and efficiency from tests (excluding machines for traction vehicles) Ingestion-build-117251 BS EN ISO 4126-3 specifies

BS EN ISO 4126-3 specifies the requirements for a product assembled from the in-series combination of safety valves or CSPRS (controlled safety pressure relief systems) according to BS EN ISO 4126-1

and where result values of BS EN 1367-1 test method do not describe correctly aggregate performance in extreme conditions

large electromagnetic forces are experienced by the windings due to the combination of high magnetic fields and high current density

NOTE: In order to comply with this standard

It also allows for the application of movement prior to and/or during fire testing

Rotating electrical machines - Standard methods for determining losses and efficiency from tests (excluding machines for traction vehicles) Ingestion-build-117251 BS EN ISO 4126-3 specifiesBS EN 60034 2 1: 2007 is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses. The Standard applies to d. c. machines and to a. c. c synchronous and induction machines of all sizes within the scope of IEC 60024 1.
