Operating time check of OVS1, OVG1, UVS1, UVG1 IDMT curves
•
Apply a rated voltage at the IDMT time multiplier setting 10.0 of the relay.
•
Change the voltage from the rated voltage to the test voltage quickly and measure the
operating time. Test voltage: 1.5
×
(setting voltage) or 0.5
×
(setting voltage)
•
Calculate the theoretical operating time using the characteristic equations shown in Section
2.4.9.1 and 2.4.9.2. Check the measured operating time within
±
5%.
6.5.1.10 Voltage and Synchronism Check Elements
The testing circuit is shown in Figure 6.5.1.7. If scheme switch [3PH-VT] is set to "Bus", the
three-phase voltage simulates the busbar voltage, and the single-phase voltage simulates the line
voltage. If the switch is set to "Line", the opposite is true.

Figure 6.5.1.7 Testing Synchronism Check Elements
When testing OVL2, UVL2 and SYN2, the single-phase voltage must be applied to terminal 17
and 18, instead of 15 and 16 and 3PH-VT is set to "Line".
Voltage and synchronism check elements and their output signal number are listed below. OVL2,
UVL2 and SYN2 are used for two-breaker autoreclose and provided in Model 300s and 501.
