The guide does not cover motors applied in solid-state switched adjustable speed drives. This standard applies to devices for separate mounting and to devices supplied integrally with other equipment. Grounding electrode techniques, pole ground values, and system ground grid values are not addressed or considered in this document. Part 1 covers the insulation surge withstand strength of motors and generators with windings having form-wound multi-turn coils and the application of surge protection to form-wound multi-turn coil motors.

An additional section discusses several special methods that may be used to improve lightning performance. Report error on page.
The faster, easier way to work with standards. This standard defines the terms used; defines the quantities to be measured; describes test and measuring circuits which may be used; defines analogue and digital measuring methods required for common applications; specifies methods for calibration and requirements of instruments used for calibration; gives guidance on test procedures; gives some assistance concerning the discrimination of partial discharges from external interference.
Selection and application recommendations Article no: Functional requirements for protective devices are addressed, including varistors and bypass gaps. Preview High-voltage test techniques – Partial discharge measurements This International Standard is applicable to the measurement of partial discharges which occur in electrical apparatus, components or systems when tested with alternating voltages up to Hz or with direct voltage.

Functional requirements for alarm devices, maintenance, design and production tests, and a guide for operation are included. Surge arresters containing both series and parallel gapped structures – Rated 52 kV and less This standard applies to all metal-oxide surge arresters with gaps and housed in either porcelain or polymeric housings.
It is likely, however, that for some systems, or in some countries, the requirements on system reliability and design are sufficiently uniform, so that the recommendations of the present standard may lead to the definition of lec ranges of arresters.
