Figure 2a shows the equivalent single-phase circuit
for the compensated system.
This single-phase circuit
is able to correct power factor in alternating current power network.
In addition, the device can accommodate 36 single-phase circuits
, 12 three-phase circuits, or any combination in between.
The goal was to evaluate meters that cost less than $1,000 for a three-phase circuit or three single-phase circuits.
However, power meters that monitor three single-phase circuits are available and are included in this study.
The Dranetz Energy Platform is equipped with eight input channels - four current and four voltage - and is easily set up to monitor and record three-phase, split-phase or single-phase circuits
This is far more cost effective than running numerous single-phase circuits
because an entire data center rack can be powered with a single circuit, or two circuits for redundancy.
