Description

Our Transformer Testing services provide a complete assessment of your power transformers' health and performance, mitigating risks and ensuring optimal operational efficiency. Whether you need routine maintenance testing or a thorough diagnostic examination after an event, we offer a tailored solution to meet your specific needs. We cater to all transformer types and sizes, including:

• Power Transformers: From small distribution transformers to large power station units.
• Instrument Transformers: Current transformers (CTs) and potential transformers (PTs).
• Special Purpose Transformers: Used in various industrial applications.

Our Testing Procedures Include:

We utilize state-of-the-art equipment and follow industry best practices to deliver accurate and reliable results. Our comprehensive testing encompasses:

• Winding Resistance Measurement: Detects insulation degradation and winding faults.
• Insulation Resistance (IR) Testing (Megger Test): Assesses the quality of insulation between windings and ground, identifying potential insulation weaknesses.
• Dielectric Withstand Test (Hi-Pot Test): Verifies the ability of the transformer insulation to withstand high voltages, detecting potential insulation breakdowns.
• Turns Ratio Test: Checks the accuracy of the transformer's turns ratio, ensuring correct voltage transformation.
• Polarity Test: Determines the polarity of the transformer windings, crucial for safe and correct connection.
• Short Circuit Impedance Test: Measures the impedance of the transformer windings, providing information about its internal construction and performance characteristics.
• Open Circuit Test (No-Load Test): Determines core losses and magnetizing current.
• Transformer Oil Testing: Analysis of the transformer oil's dielectric strength, acidity, and other key parameters to identify potential contamination and degradation. This includes:
  • Dielectric Strength (Breakdown Voltage): Measures the oil's ability to withstand high voltages.
  • Acidity (Neutralization Number): Indicates the level of degradation and potential for corrosion.
  • Dissolved Gas Analysis (DGA): Detects the presence of gases produced by internal faults, providing early warning of potential problems.
• Frequency Response Analysis (FRA): Provides a detailed picture of the transformer windings' condition, identifying potential mechanical or electrical defects. This non-destructive testing method is crucial for detecting loose windings or winding deformations.
