Inverse time operation

The inverse time operation - i.e. inverse delay minimum time
(IDMT) type of operation - is available for several protection
functions. The common principle, formulae and graphic
representations of the available inverse delay types are
described in this chapter.
Inverse delay means that the operation time depends on the
measured real time process values during a fault. For example
with an overcurrent stage using inverse delay a bigger a fault
current gives faster operation. The alternative to inverse delay
is definite delay. With definite delay a preset time is used and
the operation time does not depend on the size of a fault.

Stage specific inverse delay

Some protection functions have their own specific type of
inverse delay. Details of these dedicated inverse delays are
described with the appropriate protection function.

Operation modes

There are three operation modes to use the inverse time
characteristics:



Standard delays

Using standard delay characteristics by selecting a curve
family (IEC, IEEE, IEEE2, RI) and a delay type (Normal
inverse, Very inverse etc). See chapter 2.24.1.



Standard delay formulae with free parameters

Selecting a curve family (IEC, IEEE, IEEE2) and defining one's
own parameters for the selected delay formula. This mode is
activated by setting delay type to ‗Parameters‘, and then
editing the delay function parameters A ... E. See chapter
2.24.2.



Fully programmable inverse delay characteristics

Building the characteristics by setting 16 [current, time] points.
The relay interpolates the values between given points with
2nd degree polynomials. This mode is activated by setting
curve family to ‗PrgN‘'. There are maximum three different
programmable curves available at the same time. Each
programmed curve can be used by any number of protection
stages. See chapter 2.24.3.
