IEEE - P1553/D11
Draft Standard for Voltage-Endurance Testing of Form-Wound Coils and Bars for Hydro Generators
| Organization: | IEEE |
| Publication Date: | 1 October 2021 |
| Status: | pending |
| Page Count: | 18 |
scope:
This standard applies to voltage-endurance testing of form-wound stator winding bars and coils having a mica-based insulation system with thermo-setting polyester and/or epoxy resins used in hydro generators and pumped storage generators operating in air with a rated line-to-line voltage above 4 000 V and a frequency of 50 Hz or 60 Hz.
Purpose
The purpose of this standard is to define the test parameters for the voltage-endurance test and the number of specimens to be used for each test. It also defines the acceptance criteria and the procedures for retesting in the event of a premature failure during the voltage-endurance test. The details of the test procedure are described in IEEE Std 1043TM- Recommended Practice for Voltage-Endurance Testing of Form-Wound Bars and Coils.
