2 Installation
The 78M6612 Split Phase Evaluation Board is intended for use with a 3-wire single-phase distribution
system. This 3-wire single-phase distribution system is typically sourced from a distribution transformer
with a single-phase input (primary) winding. The distribution transformer’s secondary winding has a center
tap which is defined as Neutral. Line 1 and Line 2 exist on either side of Neutral exhibiting a 180° phase
shift between them.
The 78M6612 is referenced to Neutral and measures both voltages present on Line1 and Line 2 with
respect to Neutral. Additionally, load currents flowing in both Line 1 and Line 2 are measured. The
following figure shows the 78M6612 Split Phase Evaluation Board’s measurement inputs with various
load configurations.
