Transformer Testing and Maintenance Services
At Tajalli Tech. Pvt. Ltd, we offer comprehensive transformer testing and maintenance services to ensure the reliability, safety, and performance of your electrical transformers. With our expertise and advanced diagnostic tools, we help you optimize the lifespan and efficiency of your transformer assets.
Our Services:
- Transformer Testing:
- Insulation Resistance Testing: Assessing the condition of transformer insulation to detect potential faults or weaknesses.
- Transformer Turns Ratio (TTR) Testing: Evaluating the transformer’s turns ratio to ensure proper voltage transformation and identify any winding defects.
- Magnetization Current Test: Measuring the magnetization current to assess the magnetic characteristics of the transformer and detect any abnormalities.
- Magnetic Balance Test: Verifying the magnetic balance between the phases of a three-phase transformer to ensure symmetrical loading and prevent overheating.
- PI & DAR Testing: Evaluating insulation condition and dielectric losses to predict potential failures and prioritize maintenance activities.
- Winding Resistance Measurement (WRM): Measuring the resistance of transformer windings to evaluate their condition and detect any anomalies that may indicate internal faults or degradation.
- Tan Delta (Dissipation Factor) Testing: Assessing the dielectric properties of transformer insulation by measuring the tangent of the phase angle between voltage and current, helping identify insulation deterioration.
- Sweep Frequency Response Analysis (SFRA): Analyzing the frequency response of transformer windings to detect mechanical and electrical changes caused by faults or mechanical damage.
- Transformer Oil Testing: Analyzing transformer oil for dissolved gas, moisture content, and acidity to assess oil condition and detect degradation or contamination.
2.Transformer Maintenance:
- Cleaning and Inspection: Regular cleaning and visual inspection to identify signs of corrosion, overheating, or physical damage.
- Tightening and Torque Verification: Ensuring proper tightening of electrical connections and mechanical fastenings to prevent loose connections.
- Cooling System Inspection: Inspecting and testing cooling systems to ensure optimal heat dissipation and prevent overheating.
- Bushings and Insulation Inspection: Inspecting bushings and insulation for deterioration, cracks, or contamination to maintain reliable insulation performance.
- Lubrication: Proper lubrication of moving parts such as tap changers and bushing insulators to reduce friction and wear.
- Thermal Imaging: Identifying hot spots and abnormal temperature gradients to detect issues such as loose connections or overloaded components.
3.Transformer Protection Relay Testing:
- Winding Temperature Indicator (WTI): Testing and calibration of WTI relays to ensure accurate temperature monitoring and protection against overheating.
- Oil Temperature Indicator (OTI): Testing and calibration of OTI relays to provide reliable protection against excessive transformer oil temperature.
- Buchholz Relay: Testing and verification of Buchholz relays to detect internal faults and prevent transformer damage due to faults such as short circuits or insulation breakdown.
