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.
