- Scope of delivery
- Additional equipment (specified when ordering)
Constructively the stand consists of a body where some electrical equipment, a relay, a frontal panel and a tabletop of an integrated worktable are installed.
The following items are placed inside the body:
- step-down transformers;
- module of load resistors.
The electrical diagram of the laboratory stand is depicted on the frontal panel. A module of automatic circuit breakers, a power unit BPT-615, a safety power equipment terminal MP5 Software 50, instrumentation, indicators and controls are installed on the panel.
Readings are registered according to digital ammeters and the PLC-display of the microprocessor relay.
The stand allows conducting the following operations:
- study of the safety power equipment terminal MP5 Software 50 programming;
- study of the current changes in the line phases in nominal operating mode and with different types of faults (single- , two-, three-phase short circuits);
- study of the safety power equipment terminal MP5 Software 50 operation in nominal operating mode of the line and with different types of faults (single- , two-, three-phase short circuits);
- safety power equipment terminal MP5 Software 50 remote control.
The training system is supplied with:
- a set of teaching materials and technical documentation intended for the teaching staff;
- a software.
Experiments provided
- Study of the safety power equipment terminal MP5 Software 50 and its software.
- Setting the parameters of protection against overcurrent and checking its work with different types of faults (single- , two-, three-phase short circuits).
- Setting the parameters of protection against zero-sequence overcurrent and checking its work with different types of faults (single- , two-, three-phase short circuits).
- Setting the actuation of the protective safety power equipment terminal MP5 Software 50 from external signals.
- Configuring receipt of discrete control signals, assigning commands for the protective safety power equipment terminal MP5 Software 50 and checking its work with different types of faults (single- , two-, three-phase short circuits).
- Study of operation of power unit BPT-615 for power supply of the safety power equipment terminal protection devices in “main power” and “standby power” modes.
