Transformer Monitoring and Inspection
Distribution transformer monitoring provides critical insight to your distribution network.
Distribution transformer monitoring should be a key piece of any utilities ADMS (Advanced Distribution Monitoring System) strategy. As one of the key components of the electric grid, ensuring that electricity generated at power plants reaches homes and businesses reliably, efficiently, and safely, transformers play a crucial role. They enable the grid to function as an interconnected network, efficiently delivering power from generation sources to end-users. As the grid transforms to include an ever growing number of micro-generation sites, generally transformers are further stressed. Moreover, If these devices do fail the replacement is often complicated by an on-going inventory shortage. Protect your system with distribution transformer monitors to ensure that you have the insight necessary to stay ahead of catastrophic situations.
Once transformers are installed in the field their performance and stability are often overlooked. CB-Associates brings utilities solutions for both field testing and continuous monitoring.
Transformer Monitoring
Transformers are often stressed more than previous times due to microgrid deployments and EV installation, furthermore, they are being asked to serve extended periods of time due to limited availability. The Optanode line from Grid20/20 allows utilities to dynamically monitor these assets. Armed with this information utilities can take proactive steps to improve system performance and perform maintenance before there is a catastrophic failure. The OptaNode devices can also be used in conjunction with AMI systems to identify losses in the system, either due to system issues or theft.
OptaNODE® DTM
Single-phase Distribution Transformer Monitor
The single phase Distribution Transformer Monitor consists of accurate and patented sensing, metrology and communications components, combined into a compact and lightweight self-contained device. It installs in minutes, attaching to the transformer by means of its integrated magnets. The benefits can readily be seen via the head end software.
OptaNODE® PDTM
Poly-phase Distribution Transformer Monitor
The Poly-phase Distribution Transformer Monitor (PDTM) is a robust, flexible and rapidly deployable device, designed for use in both, three-wire and four-wire applications. It may be installed using its integrated magnets or optional pole mounting kit and it will undoubtedly become a key source of information.
Transformer Testing
A faulty or improperly wired CT can cost a utility a significant amount of revenue which is generally undetected during normal operations. Simple testing can ensure that the installation was completed properly and furthermore that the equipment is still operating as specified. Testing helps identify any issues that could compromise the safety of personnel and equipment. Transformer Monitor
CT Ratio/Burden Tester
The Tester can help determine if there are installations errors, loose connections, incorrect ratios, resistance buildup, open CT’s, or manufacturers defects. The CT Ratio/Burden Tester measures and displays the primary and secondary current of the CT under test, and the ratio of the currents. It provides important in service testing for all CT’s with a secondary less than 20 Amps
