Enabling the characteristic "I-Start" The IDMT characteristic is enabled when the current exceeds the setting "I-Start". A typical setting for "I-Start" is 1.1 IB. Choice of characteristic “c-Setting” The constant “c” determines the shape of the IDMT characteristic. The settings for the standard characteristics according to B.S. 142 are: “normal inverse” : c = 0.02 “very inverse” and “long time earth fault” : c = 1.00 “extremely inverse” : c = 2.00 “logarithmic” : c = RXIDGMultiplier "k1-Setting" The multiplier k1-Setting enables the IDMT characteristic chosen by the setting of parameter c to be shifted without changing its shape. This is used for grading the operating times of a series of IDMT relays along a line to achieve discrimination. For example, in the case of the "very inverse" characteristic, the constant c = 1 and the factor k1
13.5. The operating time t is given by the equation t k I I B
1 1 Assuming a grading time of 0.5 s at 6 times the load current IB is required, the factor k1 for each of the relays is given by The characteristics according to BS 142 are set as follows: "normal inverse" : k1 = 0.14 s "very inverse" : k1 = 13,5 s "extremely inverse" : k1 = 80 s "long time earth fault" : k1 = 120 s. The multiplier k1 has no influence on the RXIDG characteristic. Typical settings: IB-Setting corresponding to load current of the protected unit I-Start 1.1 IB c-Setting according to desired characteristic for the protected unit k1-Setting according to the time grading calculation t-min 0.00

proportion of negative-sequence current component Explanation of parameters: RunOnCPU defines the processing unit which runs the function. ParSet 4..1 Parameter for determining in which set of parameters a particular function is active (see Section 5.11.). Trip 01-08 defines the tripping channel activated by the tripping O/P of the function (matrix tripping logic). Trip 09-16 corresponds to Trip 01-08 (providing tripping unit fitted). Trip 17-24 corresponds to Trip 01-08 (providing tripping unit fitted). Trip 25-32 corresponds to Trip 01-08 (providing tripping unit fitted).

Delay time delay between pick-up and tripping. I2-Setting NPS current setting for tripping. Setting restriction: not < 0.05 IN when supplied from protection cores. CurrentInp defines the current input channel. All three-phase current I/P's may be selected. The first channel (R phase) of the group of three selected must be specified. BlockInp Binary address used as blocking input. (FFALSE, TTRUE, binary input or output of a protection function). Trip Output for signalling tripping (signal address). Start Output for signalling pick-up (signal address).
