SEA Energy Power Quality Audit Case Studies: Real Problems. Real Solutions. Real ROI.
💡 The Problem: It's Not Always the Utility
In a modern industrial facility—from steel plants to textile mills—you rely on Variable Frequency Drives (VFDs), PLCs, and sensitive electronic controls.1 These necessary components are also the main source of electrical pollution, creating power quality issues that lead to:
⚠️ Equipment Failures: Unexpected shutdowns and damage to sensitive electronics (PLCs, Circuit Boards).2
📈 Massive Energy Waste: Low power factor and harmonic currents forcing equipment to run hotter and less efficiently.3
⏰ Production Downtime: Nuisance tripping of breakers and motor failures halting the entire line.
A power quality issue often costs up to 4% of a facility's annual turnover in losses and wasted energy.4 The solution starts with pinpointing the unseen enemy.
🔍 SEA Energy's Approach: Root Cause Analysis Through Data
Our methodology goes beyond simple readings. We deploy advanced Power Quality Analyzers to continuously monitor your system's waveform for a set period. This data logging captures thousands of events to perform a precise Root Cause Analysis (RCA).
Common Issue Detected | SEA Energy Measurement Focus | The Root Cause Pinpointed |
Harmonics | Current & Voltage THD (Total Harmonic Distortion) | Unfiltered VFDs and large UPS systems causing excessive heat in transformers and neutrals. |
Voltage Sags/Dips | RMS Voltage profile during load events (e.g., motor start-up) | High in-rush current from large compressors or rolling mill motors starting without proper soft-start or mitigation. |
Low Power Factor | Reactive Power ($\text{kVAR}$) and $\text{cos}\phi$ over a 24-hour cycle | Degraded or improperly sized capacitor banks, or excessive idle running of induction motors. |
✅ Case Study : VFD Tripping in a Steel Rolling Mill
Sector | Issue Before Audit | Root Cause Identified by SEA Energy | Outcome & ROI |
Heavy Industry (Steel) | Frequent, unpredictable tripping of VFDs on the main rolling mill; significant motor overheating. | Measurements showed extreme current harmonic distortion (up to 35%) from the VFDs, causing the drive protection circuits to trip. | Solution: Installation of Active Harmonic Filters (AHF). Outcome: VFD tripping eliminated, motor temperature normalized, resulting in 150+ hours of avoided downtime per year and a 14-month ROI. |
✅ Case Study : Transformer Overheating in a University
Sector | Issue Before Audit | Root Cause Identified by SEA Energy | Outcome & ROI |
Educational/Commercial | Main distribution transformer running extremely hot; high neutral current leading to nuisance breaker trips. | Measurements showed high 3rd and 5th order harmonics due to thousands of single-phase non-linear loads (PC labs, LED lighting, servers). The neutral current exceeded phase current. | Solution: Installation of a 4-Wire Active Harmonic Filter. Outcome: Transformer temperature returned to normal operating range, eliminating safety hazards and preventing a costly transformer replacement. 35,00,000 saved in capital expenditure. |
