Split-Core CT, 200A, 200A:26.6mA, 15mm (0.6") Hole Diameter, ESCT-015-200UL

Sub metering a transmission shop

Works perfectly.

The CTs work perfectly. I recommend an assortment of locking bushings be included to clamp the CTs securely against the primary cable to prevent the CT falling against other components. I used cut 1/2" and 3/4" bushing with zip-ties to do this, but a designed product might work better.

A well thought out solution to power management

This compact system worked as advertised right out of the box. I did have to tell McAfee to get lost, as it thought that this SW was a virus pit. G-Data likes the software just fine :) My application is for load shedding. That is, real-time monitoring of the current load on the incoming service lines, with relay control to disconnect loads that are basically optional (e.g. disconnect the EV charger). Software downloaded easily and immediately began communication with the meter over a 42' twisted-pair RS-485 link to the Dash software program. Data export to Excel is straightforward. I did have to use a Dremel tool to very lightly trim the CT's to fit around the main lines into the Service Entrance. That said, I definitely appreciate the compactness of the CT's they use ( mine are CT-200's ) My only complaint at this point is that I cannot arbitrarily set the beginning and ending temporal points for data export. Seems to be all or nothing.
