OTheses test sets are used for determining the di-electric BDV of insulating oils, both new and in-service ones, used in transformers, switchgear and other electrical equipments. They are suitable for field or laboratory use and will test oil to many international specification.

Our instrument has advanced functions for fully automatic tests. They enable the operator to simply prepare an oil test cell, load it with sample oil, place it in the chamber and initiate the test sequence. The test set carries out, automatically (and if necessary unattended), the series of tests as defined by the selected oil test specification. On completion of a test sequence the average break down voltage value is displayed and the value for each individual test may be recalled.

"Initial wait time, rate of rise of test voltage, intermediate stir time, settling time and number of tests" : According to many oil tests, specifications are all pre-programmed into the sequence itself and kept the test program parameters stored in memory for use when required even after power shut down. A quick five-minute test sequence is available for rapid assessment of the condition of a sample.

"Proof Test" on oil sample can also be performed. These tests allow the operator to raise the test voltage to the level the operator chooses and retains it there for a maximum of a minute to see and increases until a breakdown occurs.
