Dual Supply Winding Resistance - Raytech mini-ATOS Instruction Manual

10.2.1 Dual Supply Winding Resistance

It is also possible to measure the two transformer sides simultaneously by selecting the Dual
Supply mode. Figure 47, Shows the winding resistance measurement in dual supply mode and all
important parts are explained.
Figure 47: Winding resistance measurement in dual supply mode
The actual tap position of the primary
side (if it contains a tap changer)
The selected current that injects into the
primary winding side
The measurement table view of the
primary side
To enable or disable the temperature
corrected resistances view for primary
To turn On or turn Off the power supply
for the primary side. It is also possible to
select "Charge" mode. In charge mode,
the power supply injects current to the
primary side to increase the transformer
charging speed. But no resistance will be
measured
