Increasingly demanding technical specifications and accountability regulations are making switchgear configuration much more critical than it used to be. In the past, software for calculating and dimensioning switchgear was helpful - nowadays it's absolutely essential.
Mitsubishi Electric's MELSHORT2 is a complete software package that provides all the functions needed for successful switchgear system configuration and layout. It supports all modern international electrical engineering standards and shines with simple and reliable operation.
The program calculates the short-circuit levels and currents at all necessary points for all switchgear components, including the power supply transformer and circuit breakers, the emergency generators, the individual motor and capacitor group branch circuits and all the other power distribution circuits, down to the last circuit breaker. This makes it possible to select the ideal breaker for every task, for optimum performance and cost-efficiency.
Key features include:
- Calculation of low-voltage switchgear
- Optimum selection of circuit breakers
- Coordination with the main power supply systems
- Allowance for the start-up currents of electric motors
- Selective shut-down
- Backup protection
- Simple and secure operation
