Iranian Experts Make Adaptive Relays for Electricity Industry
“Our knowledge-based product is a single-phase adaptive reclosing relay for transmission lines. The relay designed in Iran's Electricity Clinic is able to detect the type of fault and also the time to clear the fault,” said Mahtab Khalilifar, the managing director of the knowledge-based company.
She underlined that at present, none of the world's relay manufacturers claim this adaptive feature in their commercial devices.
“If the relay is installed in the network and issues a blocking command against permanent faults and a reclosing command as soon as possible against transient faults, it has provided the greatest service to the power grid,” Khalilifar said.
In a relevant development in June, Iranian experts at another knowledge-based company had also succeeded in manufacturing a three-phase integrated 500MVA (Megavolt Ampere) supertransformer for the country’s power grid.
“This giant supertransformer is about 14 meters long, 9 meters wide, and 10 meters high, and weighs over 335 tons, and it replaces three single-phase transformers which saves about 60% of the space required for placing transformers in the substation and prevents 70% of network no-load losses,” said Mehdi Sadeqi, the managing director of the knowledge-based company.
He added that the knowledge-based product will also reduce post construction costs and facilitate the operation and monitoring process.
Sadeqi underlined that construction of the transformer started in the presence of the Iranian Energy Minister during the 23rd International Electricity Industry Exhibition in Tehran last year.
“Despite the significant complications in calculations and design of this supertransformer, we reached the testing and unveiling state within six months,” he noted.
