Aclara Technologies LLC, a provider of intelligent infrastructure solutions and a member of the utility solutions group of ESCO Technologies Inc., has unveiled eTWACS, an enhanced version of the company's TWACS power-line communications technology.
With eTWACS, Aclara says utilities now can send and receive more data over power lines than they could with earlier generations of TWACS, and power providers will have more capacity to handle tasks such as outage management, load control and distribution management. The eTWACS protocol allows concurrent, bi-directional transmission of data on all three phases of an AC electrical distribution feeder, as well as on all buses and substations simultaneously, the company adds.
"Each eTWACS-enabled meter is capable of providing significant data to the utility, including interval reads, load profiles, voltage reads, outage data and tamper notifications, as well as insight into power quality,” says Ed Kobeszka, product manager at Aclara. “With eTWACS, this data is collected both quickly and accurately."
