In today's industrial and commercial environments, electrical systems are increasingly complex. The rise of non-linear loads—such as variable frequency drives (VFDs), LED lighting, and sophisticated IT equipment—can introduce harmonic distortions into your power supply.

Left unchecked, poor power quality leads to overheated transformers, nuisance tripping of breakers, equipment failures, and hefty utility penalties.

To ensure your facility’s electrical system is operating efficiently and safely, a comprehensive Power Quality (PQ) Analysis is essential. At Oorja Technical Services, we provide specialized power quality measurement services that take the guesswork out of electrical health.

Here is what you need to know about our 7-Day Power Quality Analysis Test as per the IEEE 519 Standard.

What is the IEEE 519 Standard?

The IEEE 519 standard is the globally recognized benchmark for harmonic control in electrical power systems. It provides recommended practices and requirements for harmonic control in electric power systems, specifically focusing on evaluating harmonic compliance at the Point of Common Coupling (PCC).

Whether you are an industrial plant, a large commercial building, or a data center, adhering to IEEE 519-2014/2022 standards is crucial for maintaining a healthy relationship with your utility provider and protecting your internal assets.

Our 7-Day Measurement Methodology

A quick snapshot of your electrical system isn't enough to understand its true behavior. Facilities experience varying loads throughout the week—shift changes, weekend shutdowns, and different production cycles all impact power quality.

To capture the true picture, Oorja Technical Services conducts a 7-day continuous Power Quality analysis.

This extended measurement period captures the full operational cycle of your facility, ensuring that we don't miss intermittent issues or peak load conditions. Using advanced power quality analyzers, our experts track your system over a full week, providing accurate data for auditing and official compliance reporting.

What Parameters Do We Measure?

According to the strict requirements of the IEEE 519 standard, our 7-day analysis measures a comprehensive list of parameters. These are captured in both "Very Short Time" (3-second) intervals to catch rapid fluctuations, and "10-minute" intervals to establish sustained averages.

Our analysis includes:

• Total Voltage Distortion (THD): We measure the overall distortion of the voltage waveform, ensuring it stays within safe limits to prevent equipment overheating and malfunction.
• Individual Voltage Harmonics: Identifying the specific harmonic frequencies (e.g., 3rd, 5th, 7th) causing distortion allows us to pinpoint the exact source of the problem.
• Flicker (Pst & Plt): We measure both Short-term Flicker (Pst) and Long-term Flicker (Plt). Flicker indicates rapid voltage fluctuations that can not only cause annoying light flickering but also disrupt sensitive electronic equipment.
• Total Demand Distortion (TDD): Unlike THD (which is a percentage of the fundamental voltage), TDD measures current distortion relative to the maximum demand load. This is a critical metric for IEEE 519 compliance.
• Individual Current Harmonics: Measuring specific harmonic currents allows us to identify which non-linear loads in your facility are injecting the most noise into the grid.
