With a legacy spanning over three decades, we have established ourselves as a trusted partner for businesses seeking comprehensive electrical solutions. Our team of highly skilled electrical engineers and technicians possesses extensive experience in the design, installation, testing, maintenance, and repair of electrical systems and equipment. We are committed to delivering exceptional service and exceeding client expectations through our unwavering dedication to quality, safety, and innovation.

Electrical Testing Expertise

At PowerCom, we understand the critical importance of reliable and safe electrical systems for any organization. Our comprehensive electrical testing services encompass a wide range of equipment and systems, including circuit breakers, transformers, switchgear, protective relays, grounding systems, motor control centers, and electrical cables. We utilize state-of-the-art testing equipment and adhere to strict industry standards to ensure accurate and reliable results.

Our testing services play a vital role in preventive maintenance programs, identifying potential issues before they escalate into costly breakdowns. We offer specialized testing services for various electrical components, such as:

• Circuit Breaker Testing: We thoroughly test circuit breakers for functionality, trip characteristics, and overall performance, ensuring they operate reliably during emergencies.
• Transformer Testing: We conduct extensive testing on transformers, including insulation resistance, winding resistance, and dielectric strength, to assess their condition and identify potential faults.
• Switchgear Testing: Switchgear is crucial for the safe and efficient distribution of electrical power. Our testing ensures proper operation of interlocks, disconnects, and control circuits.
• Protective Relay Testing: Protective relays are essential safety devices that safeguard electrical equipment and personnel. We test relays for accuracy, coordination, and timely operation.
• Grounding System Testing: A properly functioning grounding system is essential for protecting personnel and equipment from electrical shocks. We conduct thorough tests to ensure grounding system integrity.

Electrical Infrared Inspections

Our team employs advanced infrared cameras to perform comprehensive inspections of electrical systems. Infrared inspections are a non-invasive and effective method for detecting potential problems, such as overheating, loose connections, and insulation degradation, which may not be immediately visible to the naked eye. Identifying these issues early allows for proactive corrective actions, preventing costly downtime and ensuring the safety of personnel and equipment.

Engineering Services

• Selective Coordination Study: By meticulously analyzing protective relay settings, we ensure proper coordination to minimize equipment damage and optimize system protection.
• Short Circuit Analysis: We perform detailed short circuit calculations to determine the prospective fault currents within electrical systems, allowing for the selection of appropriate protective devices.
• Power System Harmonic Analysis: We identify and analyze harmonic distortions in electrical systems, mitigating their potential impact on equipment performance and reliability.
• Power Quality Monitoring and Analysis: We implement comprehensive power quality monitoring systems to identify and solve issues related to voltage sags, swells, harmonics, and other disturbances.
• Project Management: With our expertise in project management, we can oversee and execute electrical projects of all sizes, ensuring timely and cost-effective completion.

Transformer Oil Analysis

The condition of transformer oil is crucial for the health and longevity of transformers. Our in-house transformer oil analysis laboratory, equipped with cutting-edge technology and staffed by highly trained technicians, provides a comprehensive range of oil testing services.

Through meticulous sampling and testing procedures, we analyze transformer oil for various parameters, including:

• Breakdown Voltage: We measure the oil's ability to withstand high voltages, indicating its dielectric strength.
• Interfacial Tension: This test reveals the oil's ability to separate from water, preventing moisture contamination.
• Dissolved Gas Analysis: We detect and quantify dissolved gases in the oil, providing valuable insights into potential internal breakdowns or overheating within the transformer.
• Moisture Content: We measure the moisture level in the oil, identifying potential sources of insulation degradation.

We provide detailed reports with our findings and recommendations for transformer maintenance based on the test results.
