The Tektronix A6901 Ground Isolation Monitor connects between mains power and test equipment without connecting protective ground, in order to safely allow referencing measurements to a low voltage instead of ground, or break ground loops.
It monitors the floating equipment ground voltage. If the voltage exceeds 40 V peak, or ground current exceeds a selectable limit of 0.5, 3.5 or 5 mA, the A6901 disconnects mains power and grounds the test equipment.
