ISA PCI-600 Primary Current Injection Device

This device is well suited for primary injection testing of protective relays. This versatile device can also be used for testing thermal, magnetic, and solid-state motor-protection relays and molded case circuit-breakers, as well as any application that requires a highcurrent source. The PCI-600's built-in timer can test the time-delay characteristics of protection relays and molded-case circuit-breakers. Once the test is initiated, the current source and the timer are automatically turned on at the next.

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.

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 ow) is displayed on
