Protection Co-ordination Module

Main Features

	Static model of power system - voltage behind subtransient reactance modelling of rotating machines
	Wide range of protective devices including:
	IDMTL relays
	Fuses
	Miniature or molded case circuit breakers (MCBs)
	Auto-reclosers
	Phase quantities used for device operation
	Fault types include L-L, L-G, L-L-G, L-L-L-G with optional fault path impedence
	Relays open switches with time delays, and can operate any switch
	Switches can be operated by more than one relay
	Other devices switch out connected element without delays

Other Features

	Default settings in library - up to 100 variations for any supported device
	Unique settings for individual relays without limit
	Device data in pre-defined tables in library
	Graphical display of device operating curves and fault currents
	Study stages end when system is switched - hold/continue facility for stepping through analysis or amending settings and re-starting
