Protection Grading & Arc Flash
IPSA comes with an extensive library of protection devices which can be quickly added to the network. Time-current coordination graphs can be plotted to determine the grading margins between protection relays, fuses and other characteristics such as motor start curves and cable or transformer damage curves.
Software developed specifically for your needs
The IPSA Overcurrent Protection Grading module is maintained to meet the up-to-date industry standards. This module is accompanied by Arc flash module, which meets the current IEEE & NFPA standards to ensure the safety of network components.

Key features of Overcurrent Protection Grading.
Modelling of protection devices
Changeable protection device parameters
Protective Device Modeller (PDM) database
Why use this module?
Each device can have any number of curves of different types.
Protection groups contain the CTs, fuses, relays for each component.
Device parameters can be varied.
The IPSA 2 Protection Grading module provides a quick, easy and reliable way of analysing protection devices and determining protection relay settings.
This module utilises accurate IPSA 2 fault level calculations to determine device and relay operating times.
Users can add new protection devices or modify existing models using the Protection Device Modeler (PDM) application which is supplied free with all copies of IPSA.
