Leakage Current Measurement Reference Design for Determining Insulation Resistance
Description
This reference design measures insulation resistance up to 100 MΩ. It has an on-board isolated 500-Vdc power supply and an isolated signal conditioning circuit to measure the leakage current. This design is useful to find leakage due to insulation breakdown in transformer and motor windings.
Features
- Leakage current measurement circuit with option for programmable current sense amplifier and switchable shunt resistorsRange of measurement: 0 to 100 MΩ with accuracy of 5% (un-calibrated)Test voltage level derived from IEEE 43-2000 (recommended practice for testing insulation resistance of rotating machinery)On-board isolated 500-V power supply to measure insulation resistanceProvision for calibration resistor on boardHardware support for start-of-frame detect allows implement IEEE1588 PTP
