EM Series Energy Meter With Rogowski CVT

We set out to make the easiest to install, most accurate meter. We started with flexible Rogowski CTs because they’re compact, lightweight, and split-core for easy installation. But we didn’t like their accuracy. So we gave them a brain so they can digitally communicate with our meter. And then it dawned on us you’d appreciate not having high voltage at the meter where you make your digital connections. So we made the voltage connection at the CT itself. Suddenly, we were measuring current and voltage in a current transducer.

We christened it the “CVT” and called the patent attorney…

The Current/Voltage TransducerTM (CVTTM) measures both voltage and current, communicating the data digitally to the meter via plug-in low
voltage connections.

Smart microprocessor enabled CVTsTM boast numerous benefits:
▪ Digitally calibrated CVTsTM are extremely accurate
▪ The accuracy is as high as a calibrated system, yet different CVTsTM can
be changed from meter to meter and the accuracy is maintained. A big
advantage for auditing, since your meter is not size specific.
▪ Plug and play installation— individual CVTsTM are digitally recognized by the
meter base and outputs are automatically scaled—no user set up is required.
▪Digital communication offers superior noise immunity compared to
traditional induced low-signal Rogowskis
▪All the high voltage connections are at the CVTTM
▪Rogowski CVTsTM are available in 4 sizes from 9” to 36” in circumference and
include several rating options from 300A to 6000A and are universally rated
for 90-600V
