Current transformer offers high accuracy

Continental Control Systems’ Accu-CT high-accuracy, split-core current transformer provides 0.2 percent linearity.

Boulder, Colo.—Continental Control Systems has launched its new Accu-CT high-accuracy split-core current transformer (CT). Engineered for use with any of the company's WattNode energy meters, the Accu-CT is cited to offer an unprecedented 0.2 percent linearity over a wide range of the rated current (1 to 100 percent of rated current).

"If users are looking for a cost-effective, revenue-grade metering solution, we've got it with the Accu-CT," said Cynthia A. Boyd, director of sales for Continental Control Systems. "The performance of this new current transformer is outstanding. The Accu-CT has a distinctive design and color that make it easy to identify a high-accuracy, revenue-grade installation. We've also included a unique latching mechanism to ensure safe single-handed installation."

Designed specifically for revenue-grade requirements, the Accu-CT complies with the ARRA (American Recovery and Reinvestment Act) and will provide for ANSI C12.1 accuracy requirements for the California Solar Initiative (CSI) (listing pending) and for ANSI C12.20 (0.5 percent accuracy) for tenant submetering and billing when used with a WattNode energy meter. Its low-voltage rating/operation (0.333-Vac output at rated current) allows for installation without a shorting block.

The UL-recognized and CE-marked current transformer is available in rated currents of 5 A, 20 A, 50 A, 100 A, 200 A, and 250 A, with inside dimensions of 0.75 inches by 0.75 inches (20 mm by 20 mm). The device features 8-foot, 22-AWG twisted-pair leads.
