Earlier this year, we introduced the Bender NGRM550 and NGRM750 relays that are now available to provide NGR open detection and ground-fault protection on low-resistance grounded applications often found at the main power transformers feeding a facility. These devices offer improved integration with multiple source systems by switching from active to passive mode when necessary.


This webinar details how to connect a computer to the NGR monitor. It will be useful for those looking to learn more about communicating with and commissioning a unit. Since the launch of the NGRM550 and NGRM750 devices, firmware for the NGRM500 and NGRM700 relays has been enhanced.

Key Topics Covered

  • Connecting to the NGRM

  • Network settings to connect to the webserver

  • Documenting the device

  • Updating the firmware with a updated .buf file
