ABB, the world’s leading provider of electrical products and automation solutions, has introduced a new voltage relay, REU610CVVHCNP01, designed to improve the protection and monitoring capabilities of distribution plant bus-lines. The new relay belongs to the ABB Relion® 610 product family and, with its advanced technology and compact design, meets the demands of modern industry for high performance and reliability.

The REU610CVVHCNP01 voltage relay is designed for overvoltage and low voltage protection of distribution station busbars, feeder and transformer overvoltage protection, motor low voltage protection, and capacitor bank protection and monitoring. The plug-in design facilitates the debugging of the switchgear and ensures the quick and safe insertion and removal of the plug-in. In addition, the REU610CVVHCNP01 in neutral ungrounded power systems, based on zero-sequence voltage measurement, can also be used for non-selective ground fault protection and to disconnect small power units from the public network during automatic transformer substation busbar voltage conversion initialization, known as island effect.

ABB’s voltage relay is KEMA certified and Norsk Veritas certified for Marine and offshore use, demonstrating its stability and reliability in harsh environments. The compact design of the 610 series is suitable for space-constrained applications, and its removable plug-in design allows for quick and easy routine maintenance.

ABB is committed to providing customers with specialized protection for utility and industrial applications, and the introduction of the REU610CVVHCNP01 further expands ABB’s product portfolio in power system protection. This product is expected to play an important role in improving the safety and stability of power systems, especially in situations where high reliability protection is required.

Concluding remarks:

The launch of ABB’s new voltage relay, the REU610CVVHCNP01, marks ABB’s continued innovation and leadership in power system protection. We expect this product to be widely used worldwide and contribute to improving the safety and efficiency of power systems.”
