Distribution Transformer Monitor
A Distribution Transformer Monitor (DTM) is a specialized hardware device that collects and measures information relative to electricity passing into and through a distribution transformer. The DTM is typically retrofit onto pole top and pad mount transformers. A pole top (above ground) or pad mount (below ground) transformer commonly powers anywhere from 5-8 homes in the US and is the last voltage transition in stepping down voltage before it gets to the home or business. Standard positioning of DTM devices occurs at the transformer bushings, but sometimes they are attached directly onto the secondary electricity lines. DTM devices commonly consist of highly accurate non-piercing or piercing sensors, onboard communications modules to transmit information, and a power supply provision. The DTM device reports to a collection engine, and/or existing SCADA/MDM system where relevant transformer data is stored and presented to the user; analytics platforms are oftentimes employed to interpret the information being captured and reported by the DTM.
==Overview==
Given its unique location within the interior of the distribution grid, the DTM – commonly referred to as an intra-grid sensor – may present real-time and/or historical information about the transformer upon which it is hosted, in addition to creating a vital ongoing information access point within the grid architecture. A series of DTM devices deployed within a distribution grid provides multiple information points that can serve merely as bellwether measurement sources for the electric utility operator, or when deployed with increased density will provide the operator with a more robust view of grid status and performance.
DTM deployments may be surgical in nature (i.e., strategically and sparingly positioned within the grid), or comprehensively positioned to reveal critical data for extended grid areas such as line segments, specific feeders, and entire substations. DTM placement and deployment density is driven by the targeted needs of the respective utility.
Remote Over-The-Air (OTA) updates / upgrades are supported by certain DTM device offerings. This OTA capability, when supported, allows the operator to perform remote configuration and / or executable code (i.e., Firmware) updates of the DTM device(s) without the need for costly truck rolls or unit replacement. By supporting OTA Firmware updates / upgrades, providers can progressively broaden and deepen the suite of data points captured by the DTM device, making it reasonably future proof, thus escalating value and relevance to the utility operator.
