Ground Fault
– Open circuit voltage
– Low frequency norm
– Low freq norm with load
– Isolation Resistance (RISO)
– Estimated position of RISO
Disconnect
– Entered cable capacitance
– Length of cable to positive terminal
– Length of cable to negative terminal
– Capacitance measured from the positive terminal
– Capacitance measured from the negative terminal
– Low frequency norm (+ terminal)
– Low frequency norm (− terminal)
– Position of disconnect
Timer
You can set a timer to perform the ground fault test and thus leave the instrument during testing. This can be an advantage if the ground fault is periodic.
– Open circuit voltage
– Low frequency norm
– Low freq norm with load
– Isolation Resistance (RISO)
– Estimated position of RISO
Tone Generator
Mode 1 sends out a medium frequency tone between positive and negative terminals. Mode 2 alternates between high and low frequency between ground and positive, and between ground and negative.
Isc
– Stationary values of Isc and Voc
Voc
– Live updated voltmeter function
