Figure 465: Average operate time of DSTPDIS according to IEC 60255-121
network models Short line and Long line (50 Hz)
SIR curves are plotted from the data which includes variation of fault location (0...
100% of zone reach, 5% step), fault type (LN, LL, LLN, LLL) and fault inception
angle (0, 30, 60, 90 degrees). Each combination has been repeated ten times giving the
total number of 26880 shots. The operate times include the delay of relay output
contacts. The SIR curves presented in
outputs (SPOs) and with Zone timer mode = "common".

Analog channel configuration

DSTPDIS has five analog group inputs which must be properly configured.
