B100 Electronic Temperature Monitor (ETM)

B100 Electronic Temperature Monitor

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 vs Gauge

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.

    What is the B100 Electronic Temperature Monitor?

    The B100 is an electronic transformer temperature monitor designed to provide accurate temperature measurement, cooling control, communications, and asset monitoring capabilities for transformer applications.

    How is the B100 different from traditional temperature gauges?

    Unlike mechanical temperature indicators, the B100 provides electronic monitoring, communications, alarms, self-diagnostics, and integration with modern utility networks and SCADA systems.  

    Can the B100 be used as a retrofit solution?

    Yes. The B100 is commonly used as a retrofit replacement for aging monitoring systems and can fit into many existing transformer monitoring applications with minimal disruption.  Learn more here.

    What communication protocols does the B100 support?

    The B100 supports common utility communications protocols including DNP3, Modbus, and IEC 61850.  You can read more about specifications here. 

    Does the B100 include self-diagnostics?

    Yes. The B100 continuously checks the health of the monitoring system and can generate alarms if measurement or hardware issues are detected. 

    Can the B100 monitor hydrogen and moisture?

    Yes. The B100 can integrate with hydrogen and moisture monitoring solutions to provide additional transformer condition information.  

    How does the B100 help prevent transformer failures?

    The B100 continuously monitors critical operating conditions and provides alarms when abnormal conditions occur, allowing utilities to identify issues before they develop into failures.  

    Can the B100 integrate with SCADA systems?

    Yes. The B100 is designed for integration with SCADA and asset management platforms to support remote monitoring and decision-making.

    Is the B100 suitable for new transformers and retrofits?

    Yes. Utilities and OEMs use the B100 for both new installations and modernization projects.  

    What types of transformer applications are best suited for the B100?
