Timothy L. O'Hearn, PE
This 5-hour course covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of three-phase, 60 Hz, liquid-filled, self-cooled, pad-mounted, compartment-type distribution transformers. These transformers are rated 10 MVA and smaller, with the high-voltage limit of 34.5 kV system nominal voltage and below, and with the low-voltage limit of 15 kV system nominal voltage and below. These transformers are generally used for step-down purposes from an underground primary cable supply. The standard covers the connector, bushing, and terminal arrangements for radial- or loop-feed systems. Either certain minimum dimensions or certain specific dimensions shall be specified. This standard does not cover the electrical and mechanical requirements of any accessory devices that may be supplied with the transformer.
This recommended practice is a useful tool that assists individuals, organizations, and suppliers involved in the specification, design, installation, and maintenance of three-phase, 60 Hz, liquid-filled, self-cooled, pad-mounted, compartment-type distribution transformers. This standard is intended for use as a basis for determining performance, interchangeability, and safety of the equipment covered and to assist in the proper selection of such equipment.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
