MIDEL Transformer Fluids Maintenance Guide

Maintaining Midel 7131 Synthetic Ester

MIDEL 7131 is a very robust fluid which is capable of giving long service, even in the most demanding of applications.

As with mineral oil, in order to ensure that MIDEL 7131 gives continued good service it is possible to monitor a number of the fluid parameters throughout the life of the transformer. Testing the fluid also has the added benefit of picking up any potential problems with the transformer before a failure occurs.

Maintaining Midel eN 1204 Synthetic Ester

MIDEL eN 1204 is a natural ester based fluid designed for long service in sealed transformer systems.

As with mineral oil, in order to ensure that MIDEL eN 1204 gives continued good service it is possible to monitor a number of the fluid parameters throughout the life of the transformer. Testing the fluid also has the added benefit of picking up any potential problems with the transformer before a failure occurs.
