IDA 200 Insulation Diagnostics System

IDA 200 Insulation Diagnostics System is designed for diagnostic measurements of electrical insulation. Examples of application areas: Power and instrument transformers, Bushings, Cables, Generators, Motors. Electrical insulation come in all three states of matter: solid (such as cellulosic paper and porcelain), liquid (such as mineral oil), and gas (such as air and SF6). Electrical insulation systems as found in the objects listed above usually consist of a combination of different materials.

The system measures the complex impedance of a specimen at a variable voltage and frequency. A Digital Signal Processing (DSP) unit generates a test signal with the desired frequency. This signal is amplified with an internal amplifier and then applied to the specimen. The voltage over and the current through the specimen are measured with high accuracy using a voltage divider and an electrometer.

For the measuring input, IDA 200 uses an advanced DSP unit that multiplies the input (measurement) signal with a reference sine voltage, and then integrates the results over a number of cycles. With this method, noise and interference is almost completely rejected - allowing IDA 200 to work with voltage levels up to 200 V and still achieve high accuracy and detail of analysis.
