Description

Introduce

Our Resin-insulated current transformers RECT Series are designed as Extended-Range current transformers, catering to billing purposes and applicable to power systems up to 600V. This series delivers a minimum Class 0.3 Accuracy for billing measurements and can be installed indoors or in outdoor enclosures. With current ratios ranging from 100:5A to 800:5A and window diameter options including 38mm, 66mm, and 78mm, RECT Series stands out with its versatility.

Application:

Power System Protection: Widely used in power system protective relays, RECT Series accurately measures currents during normal operation and fault conditions, providing essential information for protective devices.

Energy Metering: Ideal for billing purposes in energy metering systems, RECT Series offers precise measurements across a wide current range.

Industrial Applications: Suitable for industrial environments, especially in processes with significant current fluctuations, RECT Series provides accurate current measurements and protection functionality.

Features:

High Accuracy and Linearity: RECT Series maintains a minimum 0.3 accuracy level and high linearity within its designed range, ensuring reliable current measurements under various operating conditions.

Wide Range Measurement: RECT Specifications allow the product to maintain rated accuracy and burden rating while measuring from 1% to 150% of the rated current, surpassing typical metering-class requirements (5% to 100%).

Sealed Design: All RECT Series current transformers feature a sealed design, effectively isolating transformer oil from external air to prevent oil aging and enhance operational reliability.
