Measurement of RPE at Single-Phase Extension Cords with EL1
– Measurement type PE(TS) - P1 (passive)
– Extension cord plug connected to test socket
– EL1 to P1 terminals
Schematic Diagram
Wiring Diagram
Protection Class I Devices
Special Case: Line Voltage at Test Socket (for testing PRCDs)
– Measurement type PE(TS) - P1 (active)
– DUT mains plug to test socket
– Test probe P1 to P1 terminals
Schematic Diagram
Protective conductor resistance is measured between the earth-
ing contacts at the mains plug and the earthing contact con-
nected to the housing by contacting the housing with test probe
P1.
Wiring Diagram
Protection Class I Devices
Special case: permanently installed DUTs
– Measurement type PE(mains) - P1
– Test probe P1 to P1 terminals
Schematic Diagram
In the case of permanently installed DUTs, protective conductor resis-
tance is measured between the mains power earthing contact
and the earthing contact connected to the housing by contacting
the housing with test probe P1.
