standard by IEEE, 08/08/2002
Full Description
Scope
This project will revise the present Standard for Underground Single-Phase Transformers with Separable High-Voltage Connectors; High Voltage 24940 GrdY/14400 and below; Low Voltage 240/120 V and below; 167 kVA and Smaller. The scope is being expanded to include High Voltage ratings 25000 V and below and Low Voltage ratings 600 V and below.
Purpose
To update the existing Standard to reflect current requirements and revised Scope.
Abstract
Revision Standard - Superseded.Electrical, dimensional, and mechanical characteristics and certain safety features of single-phase, 60 Hz, mineral-oil-immersed, self-cooled, distribution transformers with separable insulated high-voltage connectors are covered.
