POWER QUALITY ANALYSIS & HARMONIC ANALYSIS

Modern electrical systems are increasingly complex, with widespread usage of nonlinear loads such as variable frequency drives (VFDs), inverters, UPS systems, and LED lighting. These devices, while energy-efficient, introduce harmonic distortion and negatively impact power quality—leading to operational inefficiencies, equipment failure, and costly downtime.

At CRP Control Engineers, we provide specialized Power Quality Analysis and Harmonic Analysis services designed to detect, evaluate, and resolve these issues—ensuring your electrical infrastructure operates efficiently, safely, and in compliance with global standards like IEEE 519.

What Is Power Quality Analysis?
Power Quality Analysis is the process of assessing various parameters of your electrical supply—such as voltage, current, frequency, transients, harmonics, and power factor—to identify inconsistencies that can impact equipment performance or energy consumption.
Our advanced power analyzers and data loggers allow us to detect issues like:

• Voltage dips and swells
• Flickering and notching
• Over/under voltages
• Power factor lag
• Transient spikes
• Load imbalances

What Is Harmonic Analysis?
Harmonic Analysis involves identifying and quantifying harmonic currents and voltages—electrical disturbances typically caused by nonlinear loads. Harmonics increase system losses, overheat equipment, and can result in the malfunction of sensitive electronics.

We provide detailed insight into:

• Total Harmonic Distortion (THD) in voltage and current
• Individual current harmonics components (3rd, 5th, 7th, etc.)
• Identification of harmonic sources
• Load distribution patterns
• Impact of harmonics on transformers, capacitors, and cables
• Resonance conditions and harmonic propagation

Our Power Quality & Harmonic Audit Process

1. On-Site Survey & Data Collection
   Using high-precision analyzers, we monitor your electrical system over 24 hours to several days to capture accurate readings under real-time load conditions.
2. Advanced Analysis & Diagnostics
   Our team evaluates the collected data to identify existing or potential issues and measure compliance against standards such as IEEE 519, IEC 61000, and IS 17036.
3. Detailed Reporting
   We deliver a comprehensive report featuring graphical trends, root-cause analysis, THD levels, compliance status, and system behavior insights.
4. Actionable Recommendations
   Based on findings, we propose mitigation strategies such as:
   
   • Installation of passive or active harmonic filters
   • Power factor correction units
   • Load rebalancing or phase alignment
   • Isolation transformers or detuned reactors
5. Implementation Support (Optional)
   As licensed electrical contractors, we can execute the recommended solutions as part of a turnkey service.
