These tolerances are based the following assumptions: - self-supplied relay full power (without start-up) - presence auxiliary power supply - two-phase three-phase power supply - preset trip time 100 ms no-trip time the protection disabled for current values greater than 4In, where 0.. 2. 0,3 ..05 and 1. 1,1x690 Vconc conc .. 0,2 Instantaneous active power the single phase and total system 0,02 ...2.. 0,3 1,5 External ground fault current (external source round return) 0,05 .. 0,3 2,5 Instantaneous reactive power the single phase and total system 0,02 ..The minimum value this trip regardless the type curve set (self­ protection)...8 In...25 20% S 10% 20% I 15% 60ms G 10% 20% Others 20% (1) (2) (5) 14.9. 0,5 2,5 Mains frequency ... 0,3 2,5 Reactive energy 0,02 . 1,1x690 Vconc conc 1 Residual voltage (for systems with neutral only) 10 ..5 0. 0,3 . 87/158 .5 In, greater than In, where 0..5 Model 2234 Apparatus Scale L 2778 Doc No- 2 Page No. 1,1x690 Vconc conc 1 Peak factor 0,1 ..... 1,1x690 Vconc conc ..8 and greater than where I4> 0....16 Table easurem ents Type measurement Standard operation range Range values measured the relay Range Tolerance % Phase and neutral currents 0,05 . 0,3 1,5 Internal ground fault current (internal source round return) 0,05 . 2,5 Apparent energy 0,02 .... 0,3 1,5 Total power factor 0,1 . 0,3 2,5 Active energy 0,02 .... 0,3 1,5 Phase-to-phase and phase voltages (measured the module's input and thus independent the precision relating the use any VT) 10 . 0,3 2,5 Instantaneous apparent power on the single phase and total system 0,02 ......
