A Better Test Point Voltage Sensor for Switchgear

Date held: February 9, 2022

Releasing in February 2022, the new SEL-3780 Test Point Voltage Sensor is robust and versatile—ideal as either an OEM component in source-transfer switchgear or a retrofit for existing equipment.

We have carefully designed the SEL-3780 from the ground up to be more reliable, easier to use, and easier to install than other options.

In this webinar, we cover some of the improvements that make the SEL-3780 a dependable and economical choice as a component in source-transfer switchgear, including the following:

  • User-initiated self-calibration—no factory calibration necessary.
  • Universal compatibility with IEEE 386-compliant elbows and T-bodies—simplify integration and parts inventory.
  • Quick, safe retrofit capability—no need to disconnect or cut cables.
  • Easily selectable testing and operating modes—LEDs clearly indicate the device status.
  • Self-monitoring and alarms—communicating the status to the relay helps ensure fail-safe operation.
