GE Multilin 489 Generator Management Relay 7-1

7 TESTING 7.1 TEST SETUP

7 TESTING 7.1TEST SETUP 7.1.1 DESCRIPTION

The purpose of this testing description is to demonstrate the procedures necessary to perform a complete functional test of

all the 489 hardware while also testing firmware/hardware interaction in the process. Since the 489 is packaged in a dra-

wout case, a demo case (metal carry case in which the 489 may be mounted) may be useful for creating a portable test set

with a wiring harness for all of the inputs and outputs. Testing of the relay during commissioning using a primary injection

test set will ensure that CTs and wiring are correct and complete.

The 489 tests are listed below. For the following tests refer to Figure 7–1: Secondary Current Injection Testing on page 7–2:

1. Output Current Accuracy Test

2. Phase Voltage Input Accuracy Test

3. Ground, Neutral, and Differential Current Accuracy Test

4. Neutral Voltage (Fundamental) Accuracy Test

5. Negative Sequence Current Accuracy Test

6. RTD Accuracy Test

7. Digital Input and Trip Coil Supervision Accuracy Test

8. Analog Input and Outputs Test

9. Output Relay Test

10. Overload Curve Test

11. Power Measurement Test

12. Reactive Power Test

13. Voltage Phase Reversal Test

For the following tests refer to Figure 7–2: Secondary Injection Setup #2 on page 7–12:

14. GE Multilin (HGF) Ground Current Accuracy Test

15. Neutral Voltage (3rd Harmonic) Accuracy Test

16. Phase Differential Trip Test

For the following test refer to Figure 7–3: Secondary Injection Test Setup #3 on page 7–15:

17. Voltage Restrained Overcurrent Test
