Bender Inc. Announces Newest Advancement in NGRM Technology

Bender Inc., part of the Bender Group, the global leader in ground-fault protection, is proud to announce the release of its most advanced Neutral Grounding Resistor (NGR) Monitor, the NGRM700.

EXTON, Pennsylvania -September 29, 2017 -- Bender Inc., part of the Bender Group, the global leader in ground-fault protection, is proud to announce the release of its most advanced Neutral Grounding Resistor (NGR) Monitor, the NGRM700. This protective relay offers industry-leading protection providing additional safety on high-resistance-grounded transformers and generators.  It exceeds regulatory requirements and exceeds the limitations of other devices on the market by detecting open and shorted resistors in both active and passive monitoring.  The NGRM700 can detect ground faults by monitoring AC and DC NGR current using selectable filtering.  It will also detect a neutral-to-ground fault.  It is capable of measuring phase voltages and can indicate which phase has a ground fault, which, combined with pulser control helps to make fault location faster and saves expensive downtime.  The detachable graphical display can be panel mounting or attached to the relay.  Each unit is equipped with Ethernet communications. Production units are now available for installation.

The Canadian Electrical Code Update 2018

The CE Code, C22.1-18, was made available at the beginning of 2018. While its adoption date varies by location, Canadians affected by the Code will soon need to update their knowledge and practices for new and upgraded electrical installations. Section 10, Grounding and Bonding, has been extensively re-written. The Bender NGRM700 can be used to perform the functions required by Rule 10-302, Use of Impedance Grounded Systems. (These systems are usually grounded through a neutral-grounding resistor (NGR)).

•   Ground fault on a current-carrying conductor

•   NGR failure in open mode

•   NGR failure in shorted mode

•   Ground fault on a neutral conductor

•   Ground fault on the conductor connecting the NGR to the power system
