Customer Quote: This past week, Tampa Electric (TECO) was working on power lines in Oldsmar. Somehow, in the process of their work they managed to drop one of their live 7,200-Volt lines to the ground. Directly below where they were working, we (Bright House Networks) had two Power Supply Cabinets. The High Voltage line made a direct bull's-eye on our equipment. As the Power line hit the ground it did not immediately blow its fuse. The line bounced around on the ground throwing sparks and fire everywhere and made contact with our Cabinets several times. Each time it hit the Power Supply cabinets it instantly melted holes and energized the equipment with thousands of volts and hundreds of Amps. (See pictures below) Copyright © 2008 Diversified Power Solutions, LLC 14

Burn marks on the cabinet to the right are from a 7,200 Volt power line. This put 7,200 volts on the metal of the cabinet. Copyright © 2008 Diversified Power Solutions, LLC 15

Quote These pictures only show a small part of the over-all damage to our Cabinets. When I arrived at the location and saw the damage to the exterior of the cabinets, I figured that everything inside was toast. Thankfully, I was wrong. Throughout the entire ordeal our Power Supply equipment continued to operate keeping the cable system online. Our Power supplies did switch over to standby mode once the power company's fuse finally opened and commercial power was lost to our equipment. During this event the cable system never failed to keep operating. Each of our Power supply units was protected by Diversified Power's VSS-20BH surge protectors. The only damage to any of the electronic equipment was one of the Surge Protector units was burnt up as you can see in the picture below. Had the equipment not been protected by the surge protectors, there is a high likely hood that all three Power supply unit would have been destroyed. Costing the company thousands of dollars Copyright © 2008 Diversified Power Solutions, LLC 17

This is the damaged VSS20BH. It sacrificed itself to protect the field equipment! Copyright © 2008 Diversified Power Solutions, LLC 18

Throughout the entire ordeal our Power Supply equipment continued to operate keeping the cable system online. We put a few VSS20BH units on our most troublesome sites. They worked great and eliminated the problems. Based on that, we put VSS20BH units on ALL of our sites Copyright © 2008 Diversified Power Solutions, LLC 19
