What is the TEALwatch® Power Monitor?

The TEALwatch® power monitor is a completely self-contained Linux based web server. This web server is being utilized as a power monitor with custom software and algorithms designed by TEAL Electronics. The hardware and software platforms are both very flexible and allow firmware updates to be executed over the Internet to update the TEALwatch® when required.

The TEALwatch® is powered from the power subsystem that it is monitoring, via a separate isolated power supply/voltage divider board (power/divider PCBA), which is located (with the TEALwatch®) inside the power subsystem. The TEALwatch® and power/divider PCBA are connected via two interface cables, one for power, and one for signals. The power/divider PCBA requires a 5-wire WYE connection (unless the 4-wire DELTA input option is included, please contact the TEAL Marketing Department for further details), with connections for the 3 phase voltages (Line to Neutral), Neutral, and Ground.

The user connects to the TEALwatch® with a standard Ethernet 10Base-T connection. Alternate and custom interfaces are available through optional daughter-card expansion boards. Please contact the TEAL Marketing Department for further information.

The TEALwatch® power monitor is an 8-channel monitor, sampling at a rate of 128 samples per cycle. The first 3 channels are dedicated for Voltages. The next 3 channels are dedicated for Currents. And the final 2 channels are generic and not dedicated. Note that the present version of the software is only monitoring the first 3 channels, which are Voltages. A future version will include the additional 5 channels, please contact the TEAL Marketing Department for further information. Also note that the final two channels can be monitored via a multiplexed interface for expansion to more than the two channels, but with a more limited sampling rate.
