Atec Megger-PULSAR - Manual (Page 2)

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 multiple-
channel 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.

Universal Protective Relay Test System
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.
