Transformer Field and In-Shop Services

In Field Services

Often times, all a transformer needs to maintain good working condition is to undergo minor repairs. We have the capability to do these repairs in the field:

  • Gasket Replacement
  • Vacuum Filling
  • Weld Leaks
  • Bushing Replacement
  • Remote Oil Sampler and Nitrogen Purge Valves Installation

On Site Testing

Brandon and Clark, Inc. provides these on-site tests:

  • Doble® Testing
  • Insulation Resistance Testing
  • Winding Resistance Testing
  • CT Testing
  • SFRA Testing
  • Transformer Turns Ratio (TTR) Testing

Each transformer’s test results are recorded and stored for trending analysis and recommendations made to ensure maximum life of the transformer.

Hot Oil Processing

Gas contamination and moisture are two of the most destructive agents in a transformer. Our hot oil/degassing mobile processor can eliminate the gas contaminates as well as reduce the elevated moisture levels within your mineral oil, which will extend the life of the transformer.

Commissioning and Decommissioning Services

From time to time it is necessary to take a transformer off-line, for reasons such as in-field repair, bushing and radiator removal/installation or for complete unit removal. It’s important that this task be done properly to ensure the safety of those around the equipment and for the equipment itself.

How healthy is your padmount transformer?

Protecting your Padmount

From the wind turbine’s generator comes the flow of electrical energy. This electricity’s first connection to the energy grid is the padmount or step-up transformer. This first in line piece of equipment is crucial and vital to the entire system. Failure here is simply not an option.

Motor and Generator Repair

Brandon and Clark’s electric motor and generator repair expertise will return to you a motor that is reliable and often times more efficient then when first manufactured.

Our assurances to you are:

  • All repairs will adhere to the high standards set forth by ANSI, EASA and IEEE
  • All repaired motors and generators will undergo a wide range of testing to ensure proper operation
  • Materials used in the repair process are of superior quality and reliability
