Importance of Bushing, Tap Changer & Insulation Testing
Power transformers are subjected to high electrical stress, environmental conditions, and aging factors that can degrade their performance over time. Regular bushing, tap changer, and insulation testing offers multiple benefits, including:
- Capacitance & Power Factor Testing: Detects insulation deterioration and moisture penetration.
- Dielectric Dissipation Factor (DDF) Testing: Identifies bushing degradation due to aging and electrical stress.
- Partial Discharge Testing: Detects small electrical discharges that may indicate developing faults.
- Visual & Thermal Inspection: Identifies cracks, oil leaks, and overheating issues.
- Dynamic Resistance Measurement (DRM): Detects contact wear, erosion, and resistance variations.
- Operational & Control Circuit Testing: Ensures smooth tap changer movement and control system functionality.
- Oil Analysis for On-Load Tap Changers (OLTC): Checks for carbonization and contamination in insulating oil.
- Infrared Thermal Scanning: Identifies overheating contacts and mechanical defects.
- Insulation Resistance (IR) Testing: Measures insulation quality and detects aging or moisture damage.
- Dielectric Strength Testing: Assesses the ability of insulation to withstand high voltages.
- Polarization Index (PI) Testing: Evaluates insulation health over time.
- Tan Delta (Dissipation Factor) Testing: Identifies insulation deterioration before failures occur.
