Table 5-1 Functions to Disable When Testing
5.1 Equipment/Test Setup
No calibration is necessary, as the M-3410A Intertie/
Generator Protection Relay is calibrated and fully
tested at the factory. If calibration is necessary
because of a component replacement, follow the
Auto Calibration procedure detailed in Section 5.3,
Auto Calibration.
Equipment Required
The following equipment is required to carry out the
test procedures:
1. Two Digital Multimeters (DMM) with 10
A current range.
2. Appropriate power supply for system
power.
3. Three-phase independent voltage sources
(0 to 150% of nominal voltage) with
variable phase to simulate VT inputs.
4. Three-phase independent current sources
(0 to 300% of the CT rating of 1 A or 5 A)
with variable phase to simulate CT
inputs.
5. Electronic timer accurate to at least 8
ms.
Setup
Q Q Q Q Q
NOTE : The proper voltage range for the relay is
clearly marked on the power supply label
affixed to the rear cover.
1. Connect system power to the power
input terminals TB2-28 (hot) and TB2-27
(neutral). The relay can be ordered with
a nominal input power supply of 12 V dc,
24 V dc, 48 V dc, or 120 V ac/125 V dc.
2. For each test procedure, connect the
voltage and current sources according
to the configuration listed in the test
procedure and follow the steps outlined.
When the testing of one function may
cause another function to operate
depending on the particular settings, it
is recommended the untested function
be disabled. (See Table 5-1, Functions
to Disable When Testing.)
