Test Setup Using the M4110 or the M4130
Use Figure 3.3 M4110 Setup (a), Figure 3.4 M4110 Setup (b), Figure 3.5
M4130 Setup (a), and Figure 3.6 M4130 Setup (b) to select the connection that
applies to your transformer winding configuration.
Setup for a Single-phase Transformer Test, M4110
1. Connect the M4100 test set to ground using the ground cable.
2. Connect the M4110 Leakage Reactance Interface ground cable to ground.
Make sure the M4100 and M4110 test ground leads are connected to a
common ground point.
3. Connect one end of each of the two voltage source leads across the
winding to be energized, and the other end of each to the M4110 Leakage
Reactance Interface Voltage Source Terminals. Note that these cables are
color coded and must be attached by color to the test set.
4. Connect the black and white clips on one end of the voltage sense cable
across the same winding as the voltage source leads. Connect the
connector on the other end to the Leakage Reactance Interface Voltage
Sense Terminals, observing the color coding of the leads. THE
VOLTAGE SOURCE AND VOLTAGE SENSE LEADS MUST BE
CONNECTED IN SUCH A WAY THAT THE BLACK TERMINALS
OF EACH ARE CONNECTED TO THE SAME BUSHING; AND THE
RED SOURCE AND WHITE SENSE TERMINALS ARE CONNECTED
TO THE OTHER BUSHING.
5. Jumper together the two terminals of the opposite winding (see Figure 3.3
M4110 Setup (a) or Figure 3.4 M4110 Setup (b)).
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 M4110
Leakage Reactance Interface, observing the color coding.
9. Connect the M4200c, the M4100, and the M4110 to your AC power
source.
