Bringing transformers online in less than ten minutes
Instantly upgrade your transformer into a modern data streaming unit
The energy transition could not have happened at a more critical time. Our power grids are ageing and in need of attention. To complicate matters even further, many technical power distribution specialists are getting close to retirement and it is not possible to scale the workforce to match our needs.
These developments call for a drastic change away from labour-intensive on-site assessment to a scalable, data-driven asset management strategy. The challenge is that we have no real-time transformer performance data.
We made this part easy.
A new standard by Oktogrid™
The traditional obstacles in installing measurement equipment on transformers is taking the transformer out of service and the time needed for installation of equipment.
To solve this challenge we invented a method that makes it possible to harvest and analyse performance data from any type of transformer in real time, without any downtime or tooling needed.
Our Data Collector™ is installed in less than 10 minutes and instantly turns any transformer into a modern data streaming unit.
Attach Power Source
Connect power chord to the Data Collector™
Mount sensor at the designated area and you have connected your transformer for streaming to data services
Non-invasive measurements of transformer load and performance
Measuring transformer condition and performance is difficult. We simplified the process with advanced sensors and algorithms.
The Oktogrid Data Collector is a highly specialised sensing and processing unit that is capable of non-invasively measuring physical transformer performance metrics.
Our focus is on the transformer’s electromechanical and thermodynamic behaviour.
By measuring the electromagnetic field, vibration patterns, ultrasonic acoustic emissions, and thermal variations the Data Collector™ continously gathers the information needed to track transformer performance.
Over time, and across load cycles.
