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 plant operator is in a position to decide ad hoc on the need for substitution of the transformer oil and to initiate respective measures.
The automatically generated test reports are provided in pdf-format and can be stored on a USB stick. With a weight of only 32 kg, the BA100 dielectric 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 100 kV rms.
Flashover voltage is measured with an accuracy of ±1 kV over the whole voltage range.
- The extremely short switch off time at flash over is below 5 μs. Thus the pollution of the oil by the electric arc is negligible.
- In addition, this allows nondestructive testing of synthetic oil, ester oil and silicone oil.
- The device can as well be operated on 85 V – 264 V (50Hz/60Hz) AC voltage supplies or 12 V DC power supplies.
