B100-Series

B100 Electronic Temperature Monitor (ETM)

The B100 Series Electronic Temperature Monitor (ETM) is a complete monitoring solution for any distribution, transmission or generation transformer. The B100 ETM is an analog gauge replacement that provides accurate indication of problems inside the transformer via fault gas detection. Additionally, add on a hydrogen sensor and/or moisture sensor for an all-in-one, low-cost solution that provides remote notification of any problems detected.

B100 Electronic Temperature Monitor (ETM)

Overview

How Does the B100 Compare to Traditional Mechanical Temperature Gauges?

Gauges are known to stick, subsequently leaving the transformer vulnerable. The B100 can replace up to five mechanical gauges. It has a robust design, and in the unlikely event that there is a problem, the device generates an immediate alert, ensuring the problem can be corrected.

What Makes the B100 Easy to Install and Maintain?

  • Installation process is simple, no software is needed
  • The LCD display is easy to read and can be seen from up to 60 feet and also can be read in bright sunlight or at night.
  • Device is easy to configure and maintain either remotely or on site

How Durable Is the B100 in Harsh Substation Environments?

The cast aluminum, powder coated enclosure is designed to be rugged and durable to protect against harsh environments created by water, dirt, dust and temperature extremes. It is treated with a chromate conversion process that helps the B100 have a long life expectancy (20+ years), even in harsh environments. Additionally, no calibration is required to maintain accuracy.

The B100 Electronic Temperature Monitor display has anti-UV coating technology which means that even in bright, direct sunlight the display is easy to read and has good contrast.

Does the B100 Monitor Hydrogen Gas Levels in Transformers?

Yes, with the addition of our hydrogen sensor, the B100 monitors hydrogen gas levels in a transformer providing users with an affordable solution.

How Does the B100 Detect Moisture in Transformer Insulation?

With the addition of a hydrogen + moisture sensor, the B100 ETM can detect problematic conditions within the transformer far before a fault occurs. Excessive moisture in the insulating paper of the windings will reduce the dielectric strength and also reduce the partial discharge inception voltage. As a result, the transformer is more susceptible to faults.
