Insulation Resistance Test

By applying a voltage to the dielectric barrier and measuring to specifications, this test verifies insulation integrity and proper installation.

Winding Resistance Test

This type of test ensures correct connections and verification of no serious misalignments or open connections.

Transformer Turns Ratio Test

This test measures the turns ratio of the transformer in the primary and secondary coils. It also verifies that the actual voltage matches the specified voltage ratio of the initial design.

Visual Inspections

Visual inspections as part of your predictive maintenance program check for cleanliness, cracked insulators and bushings, paint condition, oil levels, oil leaks, and grounding state.

Treatment / Oils

Advanced mobile oil processing equipment provides vacuum, filtration, degassing, and dehydration of fluids/oils to restore dielectric strength and insulation characteristics.

Oil Analysis

Proper oil analysis is critical to determining the operating efficiency of a transformer, preventing sludge formation, and maintaining cooling capacity.

Maintenance

Proactive Maintenance

Electric power is the key element of your business. We understand that it is essential to your operations, however, it can also be dangerous and expensive. Although large power transformers are among the most reliable pieces of equipment used in electrical power systems, failures do happen. The need to replace a transformer means financial and productivity losses. In many cases, a transformer can be saved if the problem is anticipated and detected before it becomes serious.

Benefits of Proactive Maintenance

Routine inspection and scheduled maintenance will eliminate unplanned downtime and improve your bottom line while maintaining uninterrupted power generation. Ensuring the continued reliability of electrical distribution systems. Minimize emergency repairs. Ensure optimal system performance, efficiency, and security.

Preventive Maintenance

The continued efficiency of electrical systems requires proper analysis, interpretation, and service recommendations. Cousus' experienced field technicians provide complete preventative maintenance testing services to ensure reliable operation of new and existing transformers and will also compare the results to baseline measurements to determine the overall health of the transformer.
