Microohmmeter IKS-30A

Microohmmeter IKS-30A

The microohmmeter IKS-30A is an universal device that is suitable for measuring transient resistances and for measuring the resistance of circuits having a large inductance, such as windings of power transformers. Due to the wide range of measured resistances (from 1 μΩ to 100 kΩ), the device also allows to measure the resistance of Сurrent Transformer (CT) and voltage transformer (VT) windings. Providing short measurement time and high accuracy, the IKS-30A will become the optimal device for teams serving 35-110 kV substations.
Thanks to the Bluetooth interface, the device can be controlled remotely by competer or tablet. Also, using the program, it is possible to recording results of three-phase/single-phase transformers and display a test report. In the software for the laptop, in addition to the functions of remote control of the measurement and generation of the test report, there is a function for converting resistance by temperature.
The device has a built-in damping circuit to dump the energy accumulated in the magnetic circuit during the measurement and to quickly reduce the current in the winding to safety level after the measurement.
