1 Model general description
The following functionalities are modelled:
4 Three-phase non-directional overcurrent protection with definite-time or IDMT characteristic, low-stage and high-
stage elements (“51P-1(1)”, “51P-1(2)”, “51P-2(1)” and “51P-2(2)” block)
2 Three-phase non-directional overcurrent protection, definite time instantaneous-stage elements (“50P/51P (1)” and
“50P/51P (2)” block)
2 Three-phase directional overcurrent protection with definite-time or IDMT characteristic, low-stage elements (“67-1
(1)” and “67-1 (2)” block)
Three-phase directional overcurrent protection with definite-time or IDMT characteristic, high-stage element (“67-2”
block)
4 Earth fault non-directional overcurrent protection with definite-time or IDMT characteristic, low-stage and high-
stage elements (“51N-1(1)”, “51N-1(2)”, “51N-2(1)” and “51N-2(2)” block)
1 Earth fault non-directional overcurrent protection, definite time instantaneous-stage elements (“50N/51N ” block)
2 Negative sequence overcurrent protection elements (“46(1)”, “46(2)” block)
1 Phase discontinuity protection element (“46PD” block)
Three-phase thermal overload protection for cables element (“49F” block, simplified logic)
3 residual overvoltage elements (“59G(1)”, “59G(2)”, “59G(3)” block )
3 phase overvoltage elements (“59(1)”, “59(2)”, “59(3)” block )
3 phase undervoltage elements (“27(1)”, “27(2)”, “27(3)” block )
1 positive sequence undervoltage element (47U+)
1 negative sequence overvoltage element(47O-)
Automatic reclosing (“79” block). Please configure the “Tab page” of the “79” block to set the reclosing/lockup logic.
Please note that the protective functions not available in the current version of the relay must be disabled manually by the
user.
