PS Power Controls provides expert Harmonic Testing and Power Quality Audit Services in Chennai. In modern industries, non-linear loads like VFDs, UPS, and LED lighting introduce harmonic distortions that can cause overheating, transformer failure, and electronic card damage.
Professionally trained engineers use state-of-the-art ALM-36 Load Managers and Class-A Power Quality Analyzers to measure, record, and analyze your electrical network. We deliver actionable insights to mitigate harmonics and achieve standard compliance.
Why You Need a Harmonic Study
Equipment Health
Prevent premature failure of capacitors, motors, and transformers caused by excessive harmonic heating.
IEEE 519 Compliance
Ensure your facility meets international standards for Total Harmonic Distortion (THD) limits at the Point of Common Coupling (PCC).
Energy Savings
Harmonics cause "skin effect" and higher losses in cables. Mitigating them directly reduces technical energy losses.
Nuisance Tripping
Identify the root cause of random breaker trips and electronic card failures in your automation systems.
Our Testing Methodology
We follow a rigorous process to ensure accurate data collection and analysis:
1. Site Survey
Identifying critical non-linear loads and measurement points (Transformer secondary, PCC, and individual feeders).
2. Data Logging
Installing Power Quality Analyzers to record voltage, current, power factor, and harmonics (up to 50th order) over a 24-hour cycle.
3. Analysis & Reporting
Analyzing recorded data for THD-V, THD-I, unbalance, sags/swells, and neutral currents. Generating a detailed report with observations.
4. Solution Design
Recommending specific solutions such as Detuned Reactors, Active Harmonic Filters (AHF), or Passive Filters based on the measured harmonic spectrum.
