Electric meters, current transformers
Power measurement: Continental Control Systems to highlight enhanced electric power meters and current transformers at Solar Canada 2014.
Electrical measurement: Continental Control Systems announced that it will preview enhancements to its revenue-grade electric power meters and highlight its ACT® line of high-accuracy, split-core current transformers (CTs) at Solar Canada 2014 in Toronto, Dec. 8-9, at booth 411.
A key highlight will be the company's WattNode® Revenue meters, which are compliant to ANSI C12.1 and will be fully compliant to ANSI C12.20, ensuring the highest possible precision for applications demanding revenue-grade accuracy and revenue-grade requirements. Designed with affordability and functionality in mind, the standard line of WattNode energy meters provides line-powered single- and three-phase, wye, or delta configurations of up to 600 Vac and loads to 6000 Amps.
"As Canada's premier solar power event, Solar Canada in Toronto allows us to demonstrate a higher valued meter with more features and increased accuracy, in addition to our extended line of high-accuracy current transformers," said Cynthia A. Boyd, director of sales for Continental Control Systems.
WattNode Revenue meters are based on a compact design at a competitive price making them an ideal OEM design-in for PV production monitoring. Featuring support for the Modbus®, BACnet®, or LonTalk® communications protocol or a pulse output, these cost-effective energy and power meters complement the company's line of high-accuracy, revenue-grade CTs.
The meters are designed for 120/208/240 Vac or 277/480 Vac applications and are UL- and CE-marked. This next quarter, WattNode Revenue meters will be calibrated using NIST-traceable equipment following the procedures specified by the ANSI C12.20 metering standard ‹ each will then be supplied with a certificate of calibration. In addition to revenue-grade, bidirectional energy (kWh) metering, the networkable WattNode Revenue meters provide dozens of additional measurements, including bidirectional power, demand, peak demand, reactive power, voltage, current, power factor, and line frequency.
The company's expanded line of the ACT revenue-grade, split-core CTs will also be front and center at Solar Canada 2014. The ACT product line provides IEEE C57.13 class 0.6 revenue-grade accuracies along with a UL listing for energy management equipment in accordance with UL 2808 and CSA/Canada 61010-1. The result is CTs for use on loads up to 600 Amps that combine the ease of installation of an opening current transformer with the accuracy normally associated with solid-core CTs. With 333.33 mVac output, they are an ideal companion to the WattNode Revenue meter for revenue-grade electric power metering applications. The company's new ACT-1250 offers an innovative oblong design and small footprint, enabling users to accommodate larger parallel circuits than the standard-sized CT.
