Electrical Measurement & Testing Services in Malaysia
Precision Measurement & Testing
for Renewable Energy Systems
Managing electrical infrastructure in today’s energy environment requires more than just routine checks—it demands precision, clarity, and compliance. As systems grow in complexity, issues like voltage imbalance, harmonics, or inverter malfunctions can significantly impact performance and safety.
At VELLD, we specialise in high-precision Measurement & Testing services that empower you to take control of your electrical system’s performance. From load profiling and power quality assessments to inverter testing and anti-islanding evaluations, our on-site services provide actionable data on key metrics such as voltage, current, harmonics, flicker, power and power factor. Backed by advanced technology, certified engineers, and years of field experience, we deliver insights that help clients troubleshoot issues, optimise operations, and meet regulatory requirements with confidence.
Clients We Work With
Large-Scale Solar Developer
For a leading LSS developer, VELLD conducted rigorous inverter testing to verify system performance prior to grid integration. Our validation process ensured that the plant’s output met interconnection standards, enabling smoother commissioning and long-term operational reliability.
Utility Substation Operator
We worked with a utility substation operator to perform detailed power quality monitoring at the Medium Voltage PMU (below 33kV). By capturing real-time data on voltage, current, flicker and harmonics, our team helped evaluate solar PV impact to the grid and ensure compliance with power quality regulations for initial operation date (IOD) requirement and providing insights for proactive grid management.
Commercial and Industrial Facility Owners
We work closely with commercial and industrial facility owners to measure their electrical demand and energy usage patterns. At designated electrical connection points, our team conducts detailed load profiling to support power system studies for self-consumption solar PV, cogeneration, waste heat recovery, and waste-to-energy (WTE) projects. These insights enable asset owners to accurately identify maximum demand, optimise energy planning, and make informed decisions for on-site generation and sustainability initiatives.
Solar PV Plant Operators
VELLD delivered comprehensive inverter testing services for solar PV plants, ensuring solar PV systems met regulatory benchmarks and interconnection criteria. Our accurate on-site measurements supported the client in achieving certification readiness and comply to commercial operation date (COD) requirement.
