Abstract :
Unison Networks Limited is currently implementing Dynamic Transformer Rating (DTR) on most of the power transformers in its distribution network. The implementation involves 50 transformers across three different regions - Hawkes Bay, Taupo and Rotorua. The DTR scheme utilizes an in-house developed DTR algorithm that has been designed based on the IEC60076-7 Loading Guide for Oil Immersed Power Transformer Standard. The algorithm samples real time data from various sensors installed in the networks and translates them into dynamic rating and insulation loss of life information for each transformer.
