IEEE Standard for Submersible Single-Phase Transformers:250 kVA and Smaller; High Voltage 34 500 GrdY/19 920 V and Below; Low Voltage 600 V and Below
Revision Standard - Active.
Electrical, dimensional, and mechanical characteristics and certain safety features of single-phase, 60 Hz, liquid-immersed, self-cooled, submersible distribution transformers are covered in this standard.
This standard is intended for use as a basis for establishing the performance, electrical and mechanical interchangeability, and safety of the equipment covered, and to assist in the proper selection of such equipment.
This standard covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of single-phase, 60 Hz, liquid-immersed, self-cooled, submersible distribution transformers with separable insulated high-voltage connectors.
These transformers are rated 250 kVA and smaller, with high voltages of 34 500 GrdY/19 920 V and below and with low voltages of 600 V and below.
These transformers are generally used for step-down purposes from an underground primary cable supply.
These transformers are typically installed in an enclosure below ground level, operated from above and suitable for continuous submerged operation.
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.
