This document provides guidelines for the application of water cooling systems for power electronics used in electrical transmission and distribution systems.

This document describes a kind of water cooling system, in which de-ionized water or de-ionized water mixed with other solutes is used as the heat transfer agent for the removal of heat from power electronic equipment. Water cooling system can be separated into main circuit, and control and protection system. Other cooling systems, in which de-ionized water is not the heat transfer agent, are excluded in this document.

This document provides guidance and supporting information for both purchaser(s) and potential supplier(s). It can be used as the basis for drafting a procurement specification and as a guide during project implementation.

NOTE Usually, the agreement between the purchaser and the supplier of the water cooling system includes specific requirements regarding contractual requirements of particular delivery. Such specific requirements will supersede the general/typical description mentioned in this document, and all functions mentioned in this document are not necessarily applicable/delivered for all systems.
