Distribution Systems And Pel Hook-Ups; Single Phase 2-Wire; Single Phase 3-Wire (Split Phase From A Center Tap Transformer) - AEMC PEL102 User Manual

3.6 Distribution systems and PEL Hook-ups

This chapter describes how the current sensors and voltage test leads have to be connected to your installation according
to its distribution system. The PEL shall also be configured (see § 4.4.3) for the selected distribution system.
Source Load

3.6.1 single Phase 2-Wire

For Single Phase 2-Wire measurements:
■
Connect the terminal N test lead to the neutral conductor
■
Connect the terminal V1 test lead to the L1 phase conductor
■
Connect the current probe to the L1 phase conductor
Ensure that the current arrow on the sensor is directed towards the
load. This ensures proper phase angle for power measurements
and other phase sensitive measurements.

3.6.2 single Phase 3-Wire (split Phase from a center tap transformer)

For Single Phase 3-Wire (Split Phase) measurements:
■
Connect the terminal N test lead to the neutral conductor
■
Connect the terminal V1 test lead to the L1 phase conductor
■
Connect the terminal V2 test lead to the L2 phase conductor
■
Connect the terminal I1 current probe to the LI phase
conductor
■
Connect the terminal I2 current probe to the L2 phase
conductor
Ensure that the current arrow on the sensor is directed towards the
load. This ensures proper phase angle for power measurements and
other phase sensitive measurements.
