Hi,

Can someone explain to me how to interpret these settings applied to protect a generator against overfluxing? Below are the settings and calibration test results.

s01_FREQ= 60 s01_UN= 120 s01_T_TRP= 0.10
s16_U1_PROT$= "ON" s16_U1= 84 s16_T_U1= 2.00
s29_UF_PROT$= "ON" s29_UF1= 1.10 s29_T_UF1= 10.00
s29_UF2= 1.30 s29_T_UF2= 5.00 s29_T_1.10= 350
s29_T_1.15= 125 s29_T_1.20= 40 s29_T_1.25= 15
s29_T_1.30= 5 s29_T_1.35= 0 s29_T_1.40= 0
s29_T_RES= 900 s29_K_ADD= 1.00 s64_CMD_RELAY$= "ON"
s64_CMD_1_1$= "UF1 TRIP"s64_CMD_1_2$= "UFT TRIP"s64_CMD_2_RELAY$=
"ON"
s64_CMD_2_1$= "UX TRIP"s64_CMD_2_2$= "U1 TRIP"

Relay Test Results for: 27 UNDERVOLTAGE PU (U1)
PICKUP VOLTS IDEAL %ERROR OK?
48.497 48.497 0.00 PASS

Relay Test Results for: 27 UNDERVOLTAGE TIMING (T U1)
MULTIPLE VALUE TIME(CY) TIME(SEC) IDEAL %ERROR OK?
0.93 45.103 122.47 2.041 2.000 2.06 PASS

Relay Test Results for: 24 V/HZ TRIP PU (UF2)
PICKUP VOLTS IDEAL %ERROR OK?
157.560 156.000 1.00 PASS

Relay Test Results for: 24 V/HZ TRIP TIMING (T FU2)
MULTIPLE VALUE TIME(CY) TIME(SEC) RANGE OK?
1.20 187.200 319.44 5.324 4.725 TO 5.525 PASS


I'm just particular with the overfluxing protection. Thanks.

Much better if we relate it to DIGSI software of Siemens:

As for test results, you need to have it in for work scope to include result explanation from the contractor to understand. We don't know how/what. Ask yourself "AM I ONLY OKAY WITH THE PASS OR FAIL RESULT?".
