Connecting up the PPA for “internal” measurements.
The breakout box is connected to a mains supply. A load is connected to the
breakout box to produce a current for the PPA to monitor. The PPA is used to
monitor the voltage and current on the connections of the breakout box. The same
voltage and current levels are applied to the 3 phase inputs of the PPA. Therefore
the display should indicate the nominally same values for all 3 phases. For the tests
in this document a 230V 50Hz mains supply was used, the load used was sinking a
current of 3.00A.
To make the connections shown in the diagram you will need the following
accessories that are not supplied with the PPA.
1 x breakout box.
1 x Load that will be connected to the breakout box.
All other connections can be made using the 4m leads supplied with the PPA.
