Low voltage main distribution (LVMD) fire
A fire occurred at a Philippine customer’s motor control center, which includes the low-voltage main distribution board, reactive current compensation, and motor control cabinets. The fire broke out at the LVMD; any complicity on the part of Bühler + Scherler could be ruled out.
The original mill was completed mid-2004 with an output of 600 t/24 h. Besides electrical planning and material supply, the plant was installed by a Bühler + Scherler assembly supervisor.
When the customer’s request for a replacement delivery was received, all levers were immediately set in motion. The purpose was to put the plant back into operation as soon as possible. After receiving the official purchase order, it was processed within 10 weeks, from production of the goods to delivery on-site.
As with the original order, the LVMD for the replacement could not be produced as usual. The overall length would then have been 17 meters. Therefore, the plant was manufactured with a greater depth. As the illustration shows, “back to back”, the overall length was shortened by half. The total order volume was 19 wooden crates with a total weight of 35 tons.
The finished plant, after acceptance by the Bühler + Scherler project manager on site, was delivered to the packer, where the main cables had also been received. Based on past experience, shock sensors were installed on the crates so that any transport damage could be traced. In addition, the 800 A circuit breakers were packed separately. It was important to eliminate as many risks as possible and to prevent damage in transit. The shipment was made by air freight, via Zurich airport to England, on to Dubai and then via Seoul to Manila to the customer.
The assembly supervisor from Bühler + Scherler dismantled the destroyed plant and prepared everything. As a result, installation was started immediately when the supplies reached the site.
Thanks to the optimal interaction of all the departments involved, the customer received top service and the plant was back in operation within 20 weeks.
