Power Supply Replacement
ZAP replaced one of three existing power supplies serving the three glass melters. The existing 1.8MW power supply was replaced with a new 3MW variable voltage transformer and a new MV vacuum contactor and disconnect switch was installed to feed the new transformer. ZAP evaluated the existing steel structure for the installation of the new Varivolt transformer. This included analysis and reinforcing of the existing steel framing, analysis and strengthening of the existing monorails, construction contractor coordination, and construction support.
