Maintenance: Electrical Safety Tests
Ground (Earth) Wire Leakage Current Tests
Perform this test to measure current leakage through the ground (earth)
wire of the equipment during normal operation.
1.
Configure the leakage tester like the circuit shown below.
2.
Connect the power cord of the device under test to the power
receptacle on the leakage tester.
3.
The device under test is to be tested at its normal operating voltage.
4.
Read the current leakage indicated on DMM.
5.
Set the polarity switch on the leakage tester to RVS (reverse).
6.
Read the current leakage indicated on DMM.
127(
If either reading is greater than the appropriate specification
below, the device under test fails. Contact GE Medical Systems
Information Technologies Technical Support.
300 µA (0.3 volts on the DMM), and the device under test is
powered from 100-120 V/50-60 Hz
300 µA (0.3 volts on the DMM), and the device under test is
powered from a centered-tapped 200-240 V/50-60 Hz, single
phase circuit
500 µA (0.5 volts on the DMM), and the device under test is
powered from a non-center-tapped, 200-240 V/50-60 Hz, single-
phase circuit
127(
Center-tapped and non-center-tapped supply circuits produce
different leakage currents and the UL and IEC limits are
different.
