Digital TWIN: A Digital Revolution
Even if all transformers are of same specifications, each becomes a unique entity to be cared for, especially when it ages. Digital Twin maps each transformer in the substation. The Digital Twin of a power transformer can also be used for controlling the actuators…
Why not use the synergies?
“OMICRONs CMC test sets are not only a solution for testing protective relays and distribution automation schemes, they enable the user to benefit from a broad range of synergies.” - Cord Mempel, Klaus Jotz
Reduction Of Losses
Technical losses in Distribution Transformers (DTs) occur because of the physical nature of the equipment and infrastructure of the power systems, i.e., I2R or copper loss – in the conductor cables, transformers, switches etc., High Technical Losses (No Load & Load losses) persist in DTs of all major utilities across India – and their losses are very high when compared to the Ideal losses for the same capacity...
Aging Assessment Of Power Transformer Insulating Oil
The most expensive and important equipment in electric power system, power transformer plays a vital role in maintaining reliable and efficient electricity supply. The condition evaluation of insulating oil of power transformer is performed by oil contamination test and the Dissolved Gas Analysis (DGA) method... - Dr. Naveen Kumar Sharma, Dr. Yog Raj Sood, Dr. Rajnish Shrivastava
