Figure 46. The Setup>Protection>General Profile 1>Testing After Initial Trip screen.
After the initial trip for an overcurrent element, testing can be performed to determine
whether the fault is temporary or permanent. Two different test sequences are available,
depending on the overcurrent element that caused the initial trip. The same test sequence
is used for faults in either direction. See Figure 46.
Testing After Initial
Trip
Each test sequence has a specified number of tests. Each test can use a PulseClosing
Technology or a Close operation followed by the configured Open Time setting.
The IntelliRupter fault interrupter does not continue a test sequence when no source
voltage is present during an open sequence. If source voltage does not return within the
configured Loss-of-Source Timeout setting (default is 300 seconds and configuration
is in the Setup>Protection>Advanced Setup screen) the IntelliRupter fault interrupter
will go directly to the Lockout state.
