"The City of Springfield lost power when a squirrel created an arc that caused the failure of a 10 MVA substation 69000 Delta-12470Y/7200 and a bank of 333 KVA regulators. I called T&R Electric and they had a rental 10 MVA and a bank of regulators on site in less than 24 hours. They picked up our failed transformer and rewound it in a timely manner while we used their rental. We have always had great service and continue to buy all of our transformers from T&R Electric Supply."
