Medium and High Voltage

Performed EPC type Medium and High Voltage installation for the Sand Plant industry and other industrial facilities. Substation maintenance and annual testing.

Plant #1:

Substation transformer sustained Bushing failure, BBES was asked to provide testing services to determine the root-cause of this damage and perform repairs. In addition to the repairs, BBES was asked to perform annual maintenance on the customer owned 15kV Distribution System.

In order to perform the repair of the Substation Transformer the plant would have to be isolated from the local power grid. In doing the option where to shut production down for 4 days or provide secondary power to the plant. BBES provided secondary power and was able to remove the substation transformer from the grid, perform the bushing replacement while also flushing and cleaning the transformer’s oil. As found test found the transformer had a high content of moisture in the Transformer Oil, lower than normal readings on the windings and a fault condition in the systems readings.

As left testing found the transformer to meet manufacture specifications and re-energization was performed 29 hours after isolation.

Plant #2:

Customer experienced multiple Distribution Circuit trips: testing and review determined system was experiencing wild-life interference with system. BBES installed Wild-Life barriers on existing M.V. terminations and eliminated circuit trips eliminating loss of revenue.

Plant #3:

Customer experienced medium voltage failure on cables feeding loadouts. Upon inspection it was learned that the medium voltage cable supplying power to this end of the plant failed. This event occurred on a Friday afternoon around 4:00pm. BBES was able to mobilize temporary power to return the loadouts to use while sourcing the needed material and returned the plant to full power by 1:00 PM Saturday afternoon.
