IEEE C37.20.3-2013 pdf download lEEE Standard for Metal-Enclosed Interrupter Switchgear (1 kV-38 kV)
1. Overview
1.1 Scope
This standard covers metal-enclosed interrupter (MEl) switchgear assemblies containing, but not limited to.such devices as interrupter switches; selector switches; power fuses; circuit breakers; controlinstrumentation and metering devices; and protective equipment. It includes, but is not specifically limitedto, equipment for the control and protection of apparatus used for distribution of electrical power.
This standard is concerned with enclosed (rather than open), indoor and outdoor switchgear assembliesrated above I kV. lt includes equipment that is part of primary and secondary unit substations. lt does nolinclude gas-insulated substation equipment or switching devices mounted integrally within a transformerenclosure.
1.2 Purpose
The purpose of this standard is to provide the usual service conditions, definition of ratings. preferredratings, design and production tests, construction requirements, an application guide, and a guide forhandling.storage.and installation for MEI switchgear.
