Universal Protective Relay Test System

Immediate error indication: Audible and visual alarms
signal when amplitude, phase angle or waveform of the
outputs is in error.

Wide-frequency bandwidth: This feature provides the
current and potential outputs to second, third and fifth
harmonic, or virtually any desired harmonic within the
operating range of the unit.

Creates user-defined waveforms for special test
applications: The operator can use any computer to
generate square waves, half-waves, sine waves and
analytical sine waves. This includes per-unit values of
amplitude, selected harmonics at various phase angles
and dc offset with exponential decay.

Built-in RS-232 interface: The interface works with
standard communication ports on any IBM or
compatible computer, even a notebook PC.

Tests high instantaneous relays: Output of two or three
current amplifier modules can be connected in parallel
to increase the maximum current available to 60
amperes (two modules) or 90 amperes (three modules)
for testing high instantaneous overcurrent relays.

Output potential of two voltage amplifier modules can
be summed together to increase the maximum potential
to 600 volts if the load is not grounded for testing high
instantaneous over-voltage relays.

SPECIFICATIONS

Temperature Range

Operating: 32 to 122° F (0 to 50° C)

Storage: -13 to +158° F (-25 to +70° C)

Humidity Range

0 to 90% RH, noncondensing

Environmentally Tested

To simulate the worst field conditions, PULSAR was tested and
certified in accordance with
Military Standard MIL-STD-810
for temperature, shock and
vibration resistance as a Class
3 instrument.

Enclosure

For field use, PULSAR can be
ordered housed in a tough,
polyethylene-plastic, sealed
enclosure.

Rubber-sealed lids protect the test set from water and dust
intrusion. Carrying handles are located on the top and sides for
convenience.

For laboratory use, PULSAR
can be ordered housed in a
laboratory style configuration.
The unit comes with panels and carrying handles mounted on the
side of the chassis.

For protection in transit, the laboratory unit comes with a rugged,
retracting-wheel carrying case. As the handle is extended, the
sturdy wheels swing out of their recesses, and the case becomes a
luggage cart and transit case in one.

The foam-lined case is designed to protect PULSAR from normal
shock and vibration in transit.

PULSAR also can be ordered without enclosures for mounting in a
standard, 19 in. (483 mm) rack.
