Conformance tests and requirements for the integrity of pad-mounted, pole-mounted and submersible distribution switchgear enclosures and associated control enclosures are included in this standard. Enclosure security and coating requirements, for…
This recommended practice describes the test procedure for the detection and measurement by the wide-band apparent charge method of partial discharges (PDs) occurring in dry-type transformers during dielectric tests, where…
General guidelines for commissioning high-voltage direct-current (HVDC) converter stations and associated transmission systems are provided. These guidelines apply to HVDC systems utilizing 6-pulse or 12-pulse thyristor-valve converter units operated as…
Identification of the key parameters that can be monitored for obtaining an indication of the condition of liquid-immersed transformers is covered by this guide. It also covers risk/benefit analysis, sensor…
This is a guide for determining applicable tests and inspection techniques for various types of large rotating electric machines. It provides short discussions relating to the capabilities and limitations of…
Criteria and test methods for determining the compatibility of cable-pulling lubricants (compounds) with cable jacket or other exterior cable covering are described in this standard. Cable-pulling lubricants are used to…
The function and life expectancy of a transformer or reactor are directly related to the temperatures experienced by its components and structures. While temperature control schemes and data-gathering activities may…
Information for reducing the risk of damage and delays during the transportation of transformers and reactors rated 10 000 kVA or higher is provided in this guide.
The performance of transformers in the presence of oscillatory transients is addressed in this guide. Oscillatory transients are typically produced by the interaction of the switching device, transformer, load, and…
