The BA75 oil tester is a portable Breakdown Analyzer for on-site testing of transformer oil. The dielectric strength of insulating oil can be tested in a simple, quick and fully automatic way, without the need to ship oil samples to a test laboratory. The automatically generated test reports are provided in pdf-format and can be stored on a USB stick.

With a weight of only 22 kg, the BA75 oil tester is ultra-light and ideal for mobile use. The test voltage is automatically controlled and increased to a maximum level of up to 75 kV rms. The extremely short switch off time at flashover is below 5 μs. Thus the pollution of the oil by the electric arc is negligible.
