Universal Protective Relay Test System
DESCRIPTION
The PULSAR
®
Universal Protective Relay Test System
represents the next generation in protective relay testing.
This one-unit, modular system lets you select the testing
capabilities you need now and expand as your
requirements change.
The PULSAR base unit includes the chassis, back plane,
and input power and control module.
Current and Voltage Amplifier Modules
The system is customized by adding a timer module and
the number of current and voltage amplifier modules
needed for specific testing applications.
For example, adding the
timer, one current
amplifier module and one
voltage amplifier module
to the base unit provides
a variable ac/dc current
and voltage output,
adjustable phase angle
and frequency settings,
and comprehensive
control, timing and
monitoring circuits. This
configuration tests singlephase relays.
Add up to three current
and three voltage amplifier modules to create a full, threephase relay test system in one portable unit.
High-Current Output
Units and Interface
Module
For high-current applications,
PULSAR can be connected to
the Multi-Amp EPOCH-20‚ and
EPOCH-II‚ High-Current
Output Units. The Multi-Amp
High-Current Interface Module
provides the control interface
between PULSAR and the
EPOCH-20 or EPOCH-II to
provide high-current, highvolt/ampere output for single-, three- or six-phase testing.
For specifications on the Interface Module, the EPOCH-20
and EPOCH-II, refer to catalog entries for these models.
Designed for Convenience
PULSAR is small and lightweight enough to be carried to
job sites by one technician. For durability, the unit is
housed in a rugged field enclosure for use at substations
and power plants. PULSAR is designed for easy setup and
operation. A standard wall outlet is the only power source
needed.
High-intensity LEDs display all outputs throughout the test,
and PULSAR automatically changes output ranges to
reduce testing time.
Manual or Computerized Control
PULSAR can be operated manually by simple, front-panel
controls or combined with any IBM
®
or compatible PC and
the Megger AVTS
TM
software package for automated
steady-state, dynamic and transient testing.
Modules slide out easily so you can
configure the system to meet your
applications.
PULSAR performs computerized
tests with IBM‚ or compatible PCs,
even notebooks.
FEATURES AND BENEFITS
■
Complete, three-phase test system: PULSAR can be
configured to provide complete three-phase variable
current, voltage, frequency, phase angle, dc voltage, dc
current, control, timing and monitoring functions.
■
Unique, modular design: PULSAR modules plug in and
slide out easily for system configuration. You can
purchase any number of modules for configuration
using one or more PULSAR units. This feature also
allows for prompt replacement of modules during
service.
■
Simple, manual control: With the system's multiplechannel outputs, you can easily change amplitude,
phase angle or frequency settings by pushing the ramp
up-and-down keys.
■
Totally automated testing: PULSAR, combined with the
advanced software capabilities of AVTS, automates
steady-state and dynamic testing, and performs transient
testing via DFR replay or EMTP/ATP simulation.
■
Steady-state and dynamic testing capability, including
dc offset: Either manually through front-panel controls
or via computer control, the operator can test virtually
any relay.
■
Performs transient tests: Acceptance tests or
troubleshooting can be accomplished by replaying
digitally recorded faults or EMTP simulations in the IEEE
COMTRADE Standard C 37.111.
■
Performs end-to-end tests: When combined with AVTS
software and a portable GPS satellite receiver, PULSAR
performs satellite-synchronized, end-to-end dynamic or
transient tests for troubleshooting complex protection
schemes.
■
Continuous LED displays: Large, high-intensity LEDs
remain active even when the test set is under computer
control so the operator can see all outputs all the time.
Amplitudes, phase angle and frequency of all current
and voltage outputs are displayed continuously and
simultaneously .
■
Automatic range changing: PULSAR automatically
performs range changes under load to reduce testing
time.

APPLICATIONS
PULSAR is designed to test virtually any relay, from simple
overcurrent relays to complex three-phase,
microprocessor-based relays requiring phase-shifting
capability. This table lists relays by IEEE device number
and matches them with the required combination of
current and voltage amplifier modules.
