Trip/Close Current
The Trip/Close module can be outfitted with an optional internal current
measurement for the Trip and Close circuits. When this option is resident
on the system, T/C Current appears below the Trip/Close virtual
connector.
This option measures the Trip and Close circuit current during a
Trip/Close test by:
• Shunting the Trip and Close currents through the Trip/Close
Current component of the Trip/Close module
• Converting the measured voltage to a digital reading
• Sending the result to the Virtual Front Panel for display on the
Graphics tab as a current waveform and on the Tabulation tab as
a peak current value

If the correct Close currents do not appear, refer to the
Doble Application Note: ”AN7: Monitoring Closing Coil Current with
the TDR9000™ Current Shunt in the Close Circuit” on page I-27
of this guide.
