Managing and reducing your energy consumption sounds like a no-brainer. Save thousands on electricity, maintain critical machine health, reduce carbon footprint? Sign me up!  Where to begin? Well, the best place to start is analyzing your energy data, but unfortunately, you can’t find that data on your electric bill—it’s barely a summary. To manage your energy, start by measuring it. Once you determine where, when, and how that energy is consumed, areas for improvement become obvious.  [Read More](https://blog.opto22.com/optoblog/energy-management-starts-with-energy-monitoring) 0 Comments [Click here to read/write comments](https://blog.opto22.com/optoblog/energy-management-starts-with-energy-monitoring#comments-listing) Topics: [Energy management](https://blog.opto22.com/optoblog/topic/energy-management), [groov rio emu](https://blog.opto22.com/optoblog/topic/groov-rio-emu), [energy monitoring](https://blog.opto22.com/optoblog/topic/energy-monitoring) ## [Case Study: Heat Treatment OEM Chooses Flexibility, Scalability](https://blog.opto22.com/optoblog/case-study-heat-treatment-oem-chooses-flexibility-scalability) Posted by [Janice Colmer](https://blog.opto22.com/optoblog/author/janice-colmer) on May 7, 2024, 11:34:13 AM - [Tweet](https://twitter.com/share) [![](https://blog.opto22.com/hubfs/MercerFunace_422.png)](https://blog.opto22.com/optoblog/case-study-heat-treatment-oem-chooses-flexibility-scalability) ### Mercer Technologies continues to innovate—adding energy cost per part. Are you considering ways to include energy monitoring in your industrial applications? Now you can hear first hand how long-time Opto customer Mercer Technologies is making it happen. The latest case study in the [*groov* case study library](https://www.opto22.com/products/groov-case-studies) features Mercer Technologies' story of innovation. See how they leverage energy monitoring data from Opto 22's *groov* product family.

When introduced in 2020, the *groov* RIO series introduced a new kind of I/O product: edge I/O. Communicating data to other systems doesn't require a PLC, PAC, or IPC. Instead, this intelligent, distributed I/O includes security, data processing, and networking to meet the needs of IIoT projects independently. Then we introduced the *groov* RIO energy monitoring unit ([GRV-R7-I1VAPM-3](https://www.opto22.com/products/product-container/grv-r7-i1vapm-3)), or RIO EMU for short, to bring the same level of connectivity to projects that require power and energy data acquisition and communication. Whether you're already using groov RIO for energy monitoring or still researching your options, the new [groov RIO EMU User's Guide](https://documents.opto22.com/2372_groov_RIO_EMU_Users_Guide.pdf) can help you understand its full capabilities and features.

In my previous blog post, “[Why Consider Energy Monitoring](https://blog.opto22.com/optoblog/why-consider-energy-monitoring)” I proposed that acquiring data was essential to any project targeted at reducing an organization's energy spend. I also touched on how the electric utility bill for industrial users can be complex. If you are considering monitoring your energy and power, a good first step would be to get a hold of and understand that bill. I thought I would analyze and share my thoughts on Opto 22’s bill, as it is probably very similar to the one for your industrial or commercial facility.

Clearly, I’m not very good at riddles, so I’ll cut straight to the answer: a current transformer, or CT. CTs are a critical part of any electrical load monitoring system, so let's take a look at how they work, the different types, how to size them, and lastly, two important aspects of installing them.
