Electrical and mechanical requirements of ventilated, non-ventilated, and sealed dry-type distribution and power transformers or autotransformers (single and polyphase, with a voltage of 601 V or higher in the highest voltage winding) are described.

Recommendations for operation and maintenance of dry-type distribution and power transformers is provided.

Recommendations for operation and maintenance of dry-type distribution and power transformers is provided.

This voluntary consensus standard sets forth the requirements for power transformer application. This standard is intended to be used as a basis for performance, interchangeability, and safety of the equipment covered, and to assist in the proper selection of such equipment. This document is a produ...

This recommended practice is focused on the wide-band measurement of the apparent charge of partial discharges (PD) which may occur in liquid-filled power transformers and shunt reactors excited by AC test voltages between 40 and 400 Hz. The major components of the PD measuring circuit including the...
