About this chapter
This chapter describes the tests that can be performed in the test section of the HMI.
11.1
Overview
The test part of the tree view in the HMI has a number of submenus for test and
viewing activities. When IED test mode is set to ON functions are inactivated so
that no signals are transmitted during testing. Under Function test modes individual
functions can be activated. The LED test are also activated here.
The submenus for binary inputs and outputs as well as the submenu titled Function
status are used to view data generated by the system. These categories of data are
outlined below.
1. Binary output values has two submenus. These are Binary output modules
(BOM) and SMT binary outputs. Under these the status of binary outputs and
SMT outputs is displayed.
2. Binary input values has two submenus. These are Binary input modules (BIM)
and SMT binary inputs. These screens show the state of all the inputs on the
Binary input modules (BIM). These are represented as digits but may also be a
number if the input is being used to receive pulses for power measurement.
3. Current protection displays a choice of functions. To view data related to these
functions it is necessary to choose one from the list and navigate to the screen
for the function in question.
4. Voltage protection displays a choice of functions available to the operator.
Function related measurements can be viewed by navigating to the screen for
each of the four functions available. Data shown here is mainly trip and start
related.
5. Frequency protection includes measurements from frequency functions.
Measurements show trip, start and similar data.
6. Multipurpose protection includes measurements showing data regarding trip
signals, start signals, current and voltage values.
7. Secondary system supervision displays a choice of functions, Current circuit
supervision and Fuse failure. Current circuit measurements include fail and
alarm signals, and fuse failure measurements consist of start data.
8. Control displays the Synchrocheck, Autorecloser, and Apparatus control
functions. The Synchrocheckand the Autorecloser functions include a number
of function related measurements such as calculated differences of
measurements and number and kind of reclosing attempts. Apparatus control
includes up to 19 functions each with their own set of measurement data
regarding interlocking, breaker and isolator conditions.
