IEEE 1553

Description / Abstract: This standard is comprised of six clauses. Clause 1 provides the scope and purpose of this standard. Clause 2 lists references to other standards, recommended practices, and guides that are useful in applying this standard. Clause 3 provides definitions that are either not found in other standards, recommended practices, and guides, or have been modified for use with this standard. Clause 4 establishes the sample size and test parameters, while Clause 5 defines the acceptance criteria. Clause 6 describes the data records that have to be maintained at the completion of the test.

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 hydrogenerators and pumped storage generators operating in air with a rated line-to-line voltage between 4 000 to 22 000 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-1996.
