Megger Relay Test System
Descriptions of Software
Included Software – Every unit comes with AVTS Basic and the PC
version of the STVI Basic Test software packages
AVTS Basic with STVI Application
Software (PC Version)
Part No.: 81302
AVTS Basic includes Online Vector, Online Ramp and Online Click-
On-Fault controls, with the ability to import, save and execute
relay specific test modules. The online tools of Vector and Ramp
provide automatic pickup, or dropout tests as well as timing and
multi-state dynamic tests. The Online Click-On-Fault tool is used to
automatically determine the reach characteristics of single or multi-
zone Distance relays using shot for single point tests, or Ramp,
Pulse Ramp, or Binary Search tools along user defined search lines.
Includes enhanced Relay Test Wizards for; Overcurrent, Differential,
Voltage, Frequency and Distance relays.
The powerful STVI screens can be run directly from a PC providing
both manual and automatic test capabilities. Intuitive menu screens
and buttons are provided to quickly and easily select the desired
test function. The Manual Test Screen power-up preset default
values maybe automatically set from the user defined configuration
screen. The user can select from a variety of test options including
manual control using the cursor up down arrows or use the mouse
control wheel to vary outputs. In addition a dynamic sequence test
includes trip and reclose up to 9 operations. An automatic ramp,
pulse ramp, or pulse ramp binary search is built in to determine
pickup or drop out of relay contacts, or perform relay specific timing
tests using the Timing Test Screen. A vector graph indicates the
relative phase angles of all of the outputs. The user may select to
have all output amplitudes metered to provide real time verification
of all of the selected outputs, or have setting values displayed. The
PC version of the STVI software includes the ability to bring all STVI
test data (from other STVI units) into file folders for retrieval and
review whenever needed. Each copy of the PC version of the STVI
software is licensed for running on one PC. Additional run keys can
be purchased seperately.
Additional Software Options
AVTS Advanced with STVI Application Part No.: 81570
AVTS Advanced includes all of the features of AVTS Basic in
addition to the powerful Test Editor and test editor tools, which
includes the Dynamic Control (with dynamic end-to-end test
capability, and Recorder features) for developing sequential tests
for virtually any function or measuring element within digital relays.
In addition, it also includes SS1 File Converter for ASPEN and CAPE
dynamic test files, End-to-End DFR Playback test macros and basic
programming Tools for creating and editing test modules. Test files
created in Advanced Test can be used with AVTS Basic.
AVTS Professional with STVI Application Part No.: 81571
Professional Test includes all of the features of AVTS Advanced
Test version plus the following additional specialized test tools. The
DFR Waveform Viewer and Playback tools are used for viewing and
analyzing IEEE C37.111 COMTRADE Standard files from digital fault
recorders and microprocessor based relays. The DFR Waveform
Viewer includes tools to recreate the analog and digital channels for
playback into protective relays for troubleshooting or evaluation. It
includes the capability to extend the prefault data as well as start
the timer associated with the event to time relay operation. These
playback test files can also be used in end-to-end tests to recreate
the transient event and evaluate the protection scheme. Test files
created in Professional can be used with Advanced Test and Basic.
Also included is the One-Touch Test Editor Control Tool for fully
automatic testing of microprocessor based relays using VB script
files or Modbus communications to automatically download relay
settings, and automatically test all the measuring elements within
the relay based upon those settings. The Waveform Digitizer
feature is also included in the Professional Test version of AVTS.
It provides tools to create digital time curves for virtually any
electromechanical relay time curve (that do not fit a time curve
algorithm). It can even be used for digitizing scanned waveforms
from a light-beam chart recorder.
IEC 61850 Megger GOOSE Configurator Software
The Megger GOOSE Configurator (MGC) provides easy to use tools
for testing relays and substations using the IEC 61850 protocol.
It is an optional software tool available with Basic, Advanced or
Professional versions of AVTS Software; see Descriptions of
Software Options above. The configurator provides relay test
engineers and technicians the capability to import parameters
from configuration files in the Substation Configuration Language
(SCL) format, and/or capture GOOSE messages directly from the
substation bus. All imported GOOSE messages will be unconfirmed
messages. Only captured messages are confirmed messages due to
the Capture feature of the MGC. Use the MGC Merge feature to
compare imported SCL and captured GOOSE messages to verify all
GOOSE messages needed to perform tests. Use them to configure
the SMRT to subscribe to preselected GOOSE messages by assigning
the data attributes to the appropriate binary inputs of the SMRT.
Use the configurator to assign the appropriate binary outputs of the
SMRT to publish GOOSE messages simulating circuit breaker status.
After the appropriate assignments of binary inputs and outputs
have been made, the test file can be saved for reuse. This provides
both manual and automatic testing of the relay using either the STVI
or AVTS software. Use standard test modules in AVTS to perform
automatic tests. Use the Dynamic Control in AVTS Advanced or
Professional to perform high speed trip and reclose tests, or use
to perform interoperability high-speed shared I/O tests between
multiple IED’s. The MGC provides mappings of Boolean and Bit
Strings and/or simulation of STRuct, Integer/Unsigned, Float and
UTC datasets.
