4. Connect one end of the voltage sense leads across the same terminals as
the voltage source leads. Connect the other end to the M4110 Leakage
Reactance Interface Voltage Input Terminals, observing the color coding
of the leads. THE SOURCE AND SENSE LEADS MUST BE
CONNECTED IN SUCH A WAY THAT THE BLACK CONNECTORS
ON THE SOURCE AND SENSE LEADS SHOULD BOTH BE
CONNECTED TO THE SAME BUSHING ON THE TRANSFORMER
UNDER TEST. ALSO, THE RED SOURCE LEAD AND THE WHITE
SENSE LEAD SHOULD BOTH BE CONNECTED TO THE BUSHING
ON THE OTHER END OF THE TRANSFORMER WINDING UNDER
TEST.
5. If performing a Per-Phase test
, jumper only the phase of the opposite
winding corresponding to the phase under test, as determined by the
winding vector diagram on the transformer nameplate, except in the case
of a zig-zag winding (see Figure 3.3 M4110 Setup (a)). If performing a
Three-Phase Equivalent Test, jumper all three line terminals of the
opposite winding.
6. Connect the M4100 safety switch to the M4110 Leakage Reactance
Interface.
7. Connect the M4100 safety strobe to the M4110 Leakage Reactance
Interface.
8. Connect the Red and Blue leads between the M4100 and the Leakage
Reactance Interface, observing the color coding.
9. Connect the M4200c, the M4100, and the M4110 to your AC power
source.
Setup for a Three-phase Transformer Test Using the M4130
1. Connect the M4100 test set to ground using the ground cable.
2. Connect the M4130 DC power supply cable between the M4130 Leakage
Reactance Module and the M4100 Safety Switch #1 connector.
3. If performing a Per-Phase test
, connect one end of the voltage source leads
across a phase of a winding (such as H
3
–H
1
or H
3
-H
0
), and the other end
to the M4130 Leakage Reactance Module Output Terminals, matching the
terminal colors to those of the lead connectors. If performing a Three
Phase Equivalent test, connect one end of the voltage source leads across
two phase terminals (the neutral bushing is not used), and the other end to
the M4130 Leakage Reactance Module Output Terminals, matching the
terminal colors to those of the lead connectors
