Our Services
⚡ ARC Power Solution – Electrical Testing & Commissioning Services
At ARC Power Solution, we specialize in providing reliable, safe, and efficient electrical Testing, commissioning and maintenance of 3.3kV to 220kV substations involves a series of procedures to ensure safe and reliable operation of the power system. These procedures include pre-energizing checks, primary equipment testing (transformers, circuit breakers, CT, PT, isolators etc.), secondary equipment testing (protection relays, control circuits), and ongoing maintenance to prevent failures. In which ARC Company performs reliable work.
We provide a full range of on-site services including transformer testing, HV & LV equipment testing, OLTC maintenance, circuit breaker testing, and more — using state-of-the-art diagnostic tools and equipment.
Transformer oil filtration is a process that removes contaminants like water, gases, and particles from the oil used in transformers to maintain its insulating and cooling properties. This process is crucial for ensuring the transformer operates reliably and extends its lifespan by preserving optimal oil quality.
✅ Our Key Services
Transformer Commissioning
Our expert team handles end-to-end commissioning of transformers, including:
- Pre-commissioning Inspection
- Functional Testing
- Relay & Protection Scheme Testing
- Load Trial Runs
- Final Reporting and Certification
Whether it’s a distribution transformer or a high-voltage power transformer, we ensure flawless performance from the very first operation.
🔧 Substation Commissioning (3.3 kV to 220 kV S/S)
We provide end-to-end commissioning, testing, and calibration services for substations up to 220 kV:
- CT Testing (Ten Delta, Ratio, Primary, Secondary, Polarity)
- PT Testing (Ten Delta, Ratio, Primary, Secondary, Polarity)
- Circuit Breaker Testing
- Isolator Operation Testing
- Lighting Arrestor Testing
🧰 Electrical Protection Equipment Testing Kit
Our team is equipped with all major kits for protection system validation:
- Transformer Testing Kit
- Circuit Breaker Timing Kit (CBT)
- HV & LV Testing Kit
- Hi-Pot Testing Kit
- Contact Resistance Measurement (CRM)
- Cable Fault Testing Kit
- Insulation Resistance Testing Kit
- Relay Testing Kit
- Current Testing Kit
- Tan Delta Testing Kit
- Oil BDV Testing Kit
🛠Circuit Breaker Testing Services
Air circuit breakers (ACBs) require regular testing and maintenance to ensure reliable operation and prevent potential failures. Testing involves visual inspections, contact resistance measurements, insulation resistance tests, and overcurrent protection testing. Maintenance includes cleaning, lubrication, and inspection of mechanical and electrical components, as well as calibration of trip units.
- High Voltage Test (Vacuum Interrupter)
- CRM Test
- Insulation Resistance Test
- Circuit Breaker Timing (CBT)
- Visual Inspection
- Contact Resistance Test
- Overcurrent Protection Test
- Trip Unit Calibration
- Secondary Injection Test
- Mechanical Operation Test
🧰 Transformer Testing (New & Old)
We offer complete testing services for both new and in-service transformers to assess their condition and operational performance.
Our testing process includes:
- Insulation Resistance Test
- Turns Ratio Test
- Winding Resistance Measurement
- Dielectric Tests (BDV, Tan Delta, etc.)
- Magnetization & Leakage Reactance Tests
- SFRA (Sweep Frequency Response Analysis)
These tests help identify early signs of wear, insulation breakdown, or internal faults, ensuring transformer reliability and reducing downtime.
✅ OLTC (On-Load Tap Changer) Maintenance & Testing
The primary purpose of a tap changer in a transformer is to regulate the output voltage by adjusting the turns ratio of the transformer windings. This allows for fine-tuning the voltage output to compensate for variations in the input voltage or changes in the load conditions on the secondary side. We provide:
- Routine Inspection and Oil Filtration
- Contact Resistance Testing
- Tap Positioning Accuracy Check
- Control Panel Calibration
- Repair or Replacement of Defective Parts
We handle all types of OLTCs – motor-operated, reactor-type, resistor-type, etc., ensuring smooth voltage regulation without interrupting the load.
