Test currents from 10 to 600 amperes AC
Also has an external-current input (0-10 A)
timer reading range 1 m.. 2 hours
The VIC Model PCI-600 is a programmable, high-current source that is designed specifically for utility-substation applications. This alternating current(ac) test device is used primarily for injection testing of protective relays. This same device can also be used for testing thermal, magnetic and solid-state motor-protection relays and molded-case circuit breakers. The PCI-600 is versatile and can also be used in many other applications that require a high-current source.
Built-in Timer
The PCI-600’s built-in timer can test the timedelay
characteristics of protectionrelays and
molded-case circuit-breakers. Once the test
is initiated, the current source and the timer
are automatically turned on at the next zerocrossing
point of the AC. The timer stops when
the PCI-600 input detects a change in the dry
contact or voltage input, or detects the removal
of the test current. The test results are then
displayed in milli-seconds and fractions of a
cycle(s) on the unit’s back-lit LCD screen (20
characters by 4 lines).
Current Source
Test currents, ranging from 10 to 600 amperes,
can be set by using the rotary dial knob on the
control panel. The test current is then measured,
and the results are displayed on the LCD screen.
When the PCI-600 is used as a current source,
the current-on time (duration of current fl ow) is
displayed on the LCD screen.
Output Current and Duration table
output @ 120 Vac output @ 240 Vac time
5.6 Vac @ 100A 9.5 Vac @ 100A 1 hour
5.3 Vac @ 200A 9.4 Vac @ 200A 5 minutes
4.9 Vac @ 300A 9.0 Vac @ 300A 2 minutes
4.6 Vac @ 400A 8.2 Vac @ 400A 1 minute
4.2 Vac @ 500A 7.5 Vac @ 500A 30 seconds
3.9 Vac @ 600A 7.0 Vac @ 600A 20 seconds
External Current Input
The PCI-600 also has an external-current input
(0 – 10 A). Both the internal current source
amplitude and the external current source measurement
readings can be viewed at the same
time.
