Overview

This part of VDE 0530 describes thermal endurance test procedures for classification of insulation systems used in a.c. or d.c. rotating electrical machines with indirect cooling and form-wound windings. The aim is to compare the test performance of a reference insulation system with proven service experience with the test performance of a candidate insulation system. The test procedures described in this standard are intended to compare the thermal endurance performance of the mainwall insulation between conductor(s) and ground and, where required by the design of the coil or bar, the insulation between the turns. The test is not intended to simulate the in-service mechanical stresses experienced by the endwinding bracing or support materials. It is also not intended to evaluate the thermomechanical deterioration by expansion and contraction of insulation during temperature cycling. DIN EN 60034-18-1 (VDE 0530-18-31) describes general testing principles applicable to thermal endurance testing of insulation systems used in rotating electrical machines. The principles of DIN EN 60034-18-1 (VDE 0530-18-31) shall be followed unless otherwise stated in DIN EN 60034-18-31 (VDE 0530-18-31). The thermal class for the insulation system refers to its maximum allowed ("hot spot") temperature. The average temperature measured in service should not exceed the allowed temperature rise according to IEC 60034-1 (VDE 0530-1). The responsible committee is DKE/K 311 "Drehende elektrische Maschinen" ("Rotating electrical machines") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
