Transformer Resistance Testing
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the Megger Transformer Ohmmeter (MTO) series of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

Oil Immersed Transfer Standard
esi SR1030 Series
The esi SR1030 transfer standards consist of 12 equal steps. These steps are available in increments of 1 (SR1030-1), 10 (SR1030-10), 100 (SR1030-100), 1k (SR1030-1k), 10k (SR1030-10k) and 100k (SR1030-100k). The esi SR1030 provides four-terminal connections for each step or for series and parallel combinations of these resistance steps using the optional Series-Parallel (SPC102), Parallel Compensation Networks (PC101) and shorting bars (SB103). This improves power dissipation, stability and errors due to variance in temperature. The esi SR1010 and esi SR1030 are used for the same applications and are alike in configuration. The esi SR1030 differs from the esi SR1010 in that it is specially sealed, and values below 100 k are filled with oil to improve changes due to thermal variations.
