Circuit Breaker Maintenance and Service

Our Transformer Oil Testing Services are conducted with utm

Our Circuit Breaker Maintenance and Service ensures that your circuit breakers operate efficiently, reliably, and safely to protect your electrical systems from faults and overloads. Regular maintenance of circuit breakers is essential to ensure that they function properly when needed and to extend their lifespan, preventing unexpected breakdowns and costly repairs.

Circuit Breaker Maintenance Services

1. Visual Inspection
   Thorough inspection of the circuit breaker for any visible signs of wear, damage, or contamination. This includes checking for any loose connections, corrosion, or misalignment of components.
2. Contact Inspection and Cleaning
   Inspection and cleaning of the contacts, ensuring that they are free from carbon buildup, dirt, or corrosion. Proper contact surfaces are essential for smooth operation and to avoid excessive arcing during operation.
3. Insulation Testing
   Performing insulation resistance tests to ensure the dielectric strength of the insulating materials is within the acceptable range and that there is no leakage current or breakdown of insulation.
4. Mechanical Operation Check
   Testing the mechanical components of the circuit breaker, such as springs, trip mechanisms, and closing mechanisms, to ensure they operate smoothly without any mechanical faults or stiffness.
5. Oil Testing and Filtration (For Oil Circuit Breakers)
   Regular testing of the oil in oil circuit breakers to check for contaminants, moisture, and its dielectric strength. We also provide oil filtration services to ensure the oil remains effective in insulating and quenching the arc.
6. Spring Charging Mechanism Check
   Verifying that the spring charging mechanism is fully operational to ensure that the breaker can close quickly and effectively when required.
7. Functional Testing
   Testing the breaker’s ability to operate under normal and fault conditions, including simulated short circuit tests to verify the breaker’s responsiveness and tripping time.
8. Calibration of Protection Devices
   Calibration of the protection settings, including the time delay and current settings, to ensure that the breaker responds correctly to different fault conditions and protects the equipment as intended.

Circuit Breaker Service Solutions

1. Repairs and Refurbishment
   If a circuit breaker is found to have faulty components, we provide repair services to restore it to full working condition. This includes replacing worn-out components such as contacts, mechanisms, and seals.
2. Upgrades and Retrofits
   We offer upgrades and retrofits to bring older circuit breakers up to current standards, enhancing performance, safety, and efficiency. This can involve installing modern protection systems, control panels, or diagnostic equipment.
3. Testing and Commissioning
   Full testing and commissioning of newly installed circuit breakers to verify that they meet all operational requirements and safety standards before being put into service.
4. Emergency Support and Breakdown Service
   We provide emergency support for circuit breaker failures, ensuring quick and efficient repairs to minimize downtime and restore your system’s protection.

ost precision and adherence to industry standards, ensuring the safety and longevity of your transformers. Accredited by NABL, we offer comprehensive testing to evaluate the physical, chemical, and electrical properties of transformer oil, as well as insights into the internal condition of the transformer. Our testing services help detect potential issues early and prevent transformer failures.

Physical Parameters

1. Appearance
   • Inspection of oil clarity and color to detect contamination or degradation.
2. Interfacial Tension
   • Measures the tension between oil and water, providing insight into oil quality.
3. Flash Point
   • Tests the temperature at which the oil vaporizes and can ignite.
4. Pour Point
   • Determines the lowest temperature at which oil remains fluid, indicating low-temperature performance.
5. Density
   • Measurement of oil density to assess purity and consistency.
6. Kinematic Viscosity
   • Measures the oil’s resistance to flow at different temperatures, indicating its ability to lubricate and insulate.

Chemical Parameters

1. Water Content
   • Detects moisture levels in the oil, which can cause insulation breakdown.
2. Total Acid Number / Neutralization Value
   • Measures the acid content in the oil, helping assess the degree of degradation.
3. Sediments and Sludge
   • Identifies impurities, such as solid particles or sludge, that can harm transformer components.

Electrical Parameters

1. Breakdown Voltage / Dielectric Strength
   • Evaluates the oil’s ability to withstand electrical stress without breaking down.
2. Specific Resistance / Resistivity
   • Measures the resistance to electrical flow, indicating insulation integrity.
3. Dielectric Dissipation Factor / Tan Delta
   • Assesses the oil’s ability to insulate by measuring energy loss in the system.

Transformer Internal Condition

1. Dissolved Gas Analysis (DGA)
   • Identifies the presence of dissolved gases in the oil, which can indicate fault conditions such as arcing or overheating.

Transformer Insulating Paper Condition

1. Furanic Compound Analysis (Furans)
   • Detects furans, which are byproducts of paper insulation degradation, helping assess transformer health.
