Y S Engineering Solution offers a comprehensive suite of transformer testing services that are crucial for maintaining the health and longevity of a transformer. While it's difficult to rank the 'top 5, ' as the importance of a test depends on the transformer's condition, the company's most essential services include: 1. Transformer Oil Testing This is a fundamental and critical test. Y S Engineering Solution analyzes the transformer's insulating oil for dielectric strength, moisture content, and acidity. This helps to identify contamination and degradation, which can lead to catastrophic failure if not addressed. 2. Insulation Resistance Testing (Megger Test) This test measures the resistance of the transformer's insulation system. A low resistance reading can indicate a breakdown in the insulation, which is a common cause of electrical faults. This test is vital for ensuring the safety and reliability of the unit. 3. Winding Resistance Testing This service checks for any abnormalities in the transformer's windings, such as loose connections, broken strands, or short circuits. It's a key diagnostic tool for identifying internal faults that can impact the transformer's efficiency and cause overheating. 4. Transformer Turns Ratio (TTR) Test The TTR test verifies the ratio of the number of turns in the primary winding to the secondary winding. It's essential for confirming that the transformer is operating according to its design specifications and for identifying potential issues like shorted turns or a damaged winding. 5. Partial Discharge (PD) Testing This specialized test detects and measures small electrical discharges that occur in the insulation. These discharges can cause gradual degradation of the insulation over time, and PD testing helps to identify and locate these issues before they can lead to a major insulation breakdown and transformer failure.
