These instructions apply to liquid filled secondary unit substation transformers manufactured by the ABB Transformer Facility at Jefferson City, Missouri. Secondary Unit Substations are typically composed of three (3) major sections: the high or medium voltage section; transformer section; and low voltage section. These sections can be close coupled whereby the sections are bolted directly together to form a single line of electrical equipment or the sections can be separated by distance and
This manual provides instructions for liquid-filled secondary unit substation transformers manufactured by ABB. It covers procedures for receiving, inspecting, and handling the transformer prior to installation, including specific guidelines for lifting and jacking to ensure safety and equipment integrity.
Transformers should not be tilted more than 15 degrees from the vertical position unless specific instructions state otherwise.
Employees must not wear polyester, acetate, nylon, or rayon clothing when exposed to electric arcs or flames.
