Power Transformer

Repair

Repair Makes Cents

Repair makes sense for your budget, your project time-line, and your environment. When Brandon & Clark repairs a power transformer, materials such as core steel and cabinetry are reused, and the old copper and insulation paper are recycled, which reduces your company's carbon footprint. Brandon & Clark's use of such procedures saves you time because you don't have to wait for a newly manufactured unit to be built, repair turn around times are typically much shorter than the time it takes to manufacture a new unit. Brandon & Clark's environmentally friendly repair procedures also save you money because you don't have to purchase new core steel or cabinetry to upgrade or repair your existing power transformer. One more way that repairing your power transformer helps you to save money is, when you choose to repair your power transformer we can assure you that when it comes time to install, the unit will fit into its previous housing dimensions. This assurance from Brandon & Clark saves you costly time, modification efforts, and gives you peace of mind.

Copper Windings

All Brandon & Clark power transformer windings are produced using copper conductor and high quality insulation. Our materials selection philosophy is: use the highest quality materials in the repair or redesign of equipment. This philosophy enables us to help customers avoid unnecessary losses and maximize the life of their equipment.

Brandon & Clark also, has experienced on staff engineers that are capable of converting your power transformer from aluminum windings to copper windings. Copper windings offer advantages in transformer losses and mechanical strength which is particularly important for industrial applications where large motor starting loads are present.

Redesign

With 54 years of combined engineering experience Brandon & Clark's engineering staff is capable of performing redesigns of power transformers. Redesign capabilities include changing primary and secondary voltages, KVA, k-factor rating and
converting designs to copper conductor material, converting windings from layer wound to continuous disc windings.

Testing & Services

Maintenance is Key

Brandon & Clark recommends that you perform routine field service testing on your mobile substation yearly to insure that your unit will be in excellent working condition when you need it the most. Field services testing on substation units includes: SFRA, DGA, TTR, resistance and Doble® testing.

Doble® Testing

Using the Doble® M4100 with the DTA database, Brandon & Clark is able to give you immediate analysis of your equipment. We can analyze and compare your test result against industry results, to distinguish emerging trends, and each device name plate and test history is located in one place, in one record, which improves the efficiency and reliability of testing and evaluation of results.

What does Doble® testing include?

• Excitation current testing to evaluate the transformer magnetizing circuit
• Power factor testing to confirm insulation integrity and quality
• Capacitance testing to measure physical changes that may have occurred to the apparatus
• Turns ratio testing to detect shorted turns or winding damage
• Capacitor bank testing detects deteriorating or failed capacitors within a bank.
• Doble bushing testing (C1/C2, hotcollar) that helps to determine individual bushing health

Brandon & Clark has a dedicated testing and field services team of Doble® trained engineers and technicians to test and evaluate your equipment in the field or in the shop.
