EOS® HIB is supplied as a 10% concentrate and can be used to retrospectively inhibit the existing in-service insulating oil in your high voltage transformer or EOS® HIB can be used to replenish an inhibited insulating oil where the level of inhibitor in the oil has reduced over time due to ageing factors. Ideally the inhibitor concentration in the trnasformer should be maintained between 0.2 and 0.4%. For further guidance contact us.

Things to remember

EOS acidity testing solution can be supplied in a single 250ml bottle or as part of a kit comprising of two bottles and a glass measuring tube in a protective case.

For a more accurate test result we would recommend the use of the EOS TransTest Service.
