BS EN IEC 60076‑22‑4 is the fourth part of a multi-series standard. This part specifies the technical specifications and test methods for the insulating liquid to water heat exchangers used in the cooling circuits of power transformers and reactors.
BS EN IEC 60076‑22‑4 is applicable to insulating liquid to water heat exchangers, using forced water, and forced liquid circuits, used on liquid immersed power transformers and reactors, with and without conservator for indoor or outdoor installation.
BS EN IEC 60076‑22‑4 on the liquid to water heat exchangers is for:
The losses occurring in the transformer are converted into heat which increases the temperature of the windings and the core. Cooling of a transformer is necessary to disperse the heat generated and water comes in very handy in this procedure.
BS EN IEC 60076‑22‑4 specifies the heat exchangers arrangements for you that are established as the current best practice of transformer insulating liquid cooling in compliance with all the requirements. It helps you in the prevention of transformer heating and can be followed by the transformer designers and manufacturers for ensuring the safety of the transformer.
BS EN IEC 60076‑22‑4 explains the end-user for approximation of the behavior of the heat exchanger under different operation conditions with the help of an example based on calculation rules. It gives you a clearer idea for manufacturing reliable and highly-efficient heat exchangers for the transformers.
