Fault Playback: This function allow the playback of COMTRADE fault description files, both binary and
ASCII, according to IEEE STD C37.111-1999. This is very useful to analyze the protection ´s behavior
against a previously recorded fault, or a simulated fault (from network simulation programs), reproducing
this transient faults recordings at a specific sampling frequency.
COMTRADE files can be directly read from a USB pendrive, select the section to be played and
analyze the response of the relay at the binary inputs in the MENTOR 12. User can edit and discard
the unneeded signal’s sections or adjust the best transformation ratio for the playback.
This makes it possible to check if the relay ´s reaction differs between the recording and its behavior
during playback, and also to analyze how other protection device operates under the same conditions.
If the GPS option is installed, it is possible to synchronize the file playback through this external time
reference.
OTHER SOFTWARE ELEMENTS
Results Manager: This module allows saving both the test results and configuration of Advanced test
functions, so that they can be repeated as desired. Results are saved in a USB pendrive.
The system can save as many tests as needed in Report files, being a way to automate tests for specific
relays. The reports can be displayed on the PC, exported and/or printed, using the Report Viewer for
Windows, which is included as standard in every MENTOR.
After any advanced function test, we can add the results to any existing report, with a new name for
this test and a description. The test is recorded with date and time and the function type. The saved
collection of user-defined and customized test routines will provide a valuable asset of ready-to-use
test tools for each relay type and protective function. The user only needs to choose one from the list
in the Results Manager and press Execute.
Binary Inputs Configuration: The MENTOR 12 has 12 (Logic) Binary Inputs grouped together in 6 isolated
pairs, in order to be able to detect the behavior of the logic outputs of the relay or protection scheme
that is being tested. The Binary Inputs can be configured to detect both Dry Contact operation signals,
or Wet Contacts, that is, a signal with voltage applied to them (1.5 or 15V threshold up to 400V pk
ac or dc). Each Binary Input can be programmed to be active High or Active Low (NO, NC).
Binary Outputs Configuration: There are 8 Binary (Logic) Outputs in the MENTOR 12, in order to be
able to program their behavior so the action of devices in the protection scheme that is being tested
can be simulated. Each Binary Output can be configured as: Relay /Open Collector, and NO/NC mode.
Binary I/O Monitor: The MENTOR 12 is permanently monitoring the Binary Inputs states, and reflecting
any change at both the screens of test results and in the Logger; furthermore, the user can also monitor
on-screen any status change of all the Binary Inputs at any time, which facilitate testing and verifying
the relay ´s reaction during the test execution.
Similarly, Binary Outputs status is displayed on the screen, monitoring the pre-programmed activity
of them at any of the functions; besides that, the user can also activate or deactivate manually any
of the Binary Outputs, if required by the simulated protection scheme, from the Binary Outputs control
on the main screen.
Meter & Measuring: Measurement configuration section to configure the settings for analog and binary
measurement. This functionality, specifically designed to test transducers with analog output in VDC
or mA DC or counters with analog or digital output by pulses, makes the conversion from the magnitude
measured at the input (V, mA, Pulses) to the units that are assumed to be the nominal ones of the
element to be tested (V, A, KVA, Kw, Kvar, Kw, time, etc) entering the ratio between both. Optical scanning
heads for capturing pulses emitted by the energy meters (non-visible infrared LED and visible) are optional
accessories available. The multifunction display in the main control panel shows the values measured
in the analog input and binary input in real time.
Logger: Automatic recording available in MENTOR 12, where any event is registered, such as the activation
of the outputs, and changes at the binary inputs and outputs. The events listing are displayed with the
time recorded for each, to correctly analyze the performance of the relay.
