Power Quality Analyzer Services on Distribution Cabinets (Electrical Power & Harmonic Audit)
Amid rapid industrial automation and the widespread use of non-linear loads, poor power quality is often the hidden culprit behind sudden operational disturbances. PT Sentra Elektrikal Prima provides professional Power Quality Analyzer (PQA) Services to diagnose, measure, and map the health of electrical networks across your facility's distribution cabinets and main switchboards.
Through precise power quality audits, we help you identify current and voltage disturbances before they damage sensitive electronic equipment or cause costly downtime.

Why Power Quality Audits Are Vital for Your Facility
Modern equipment such as Variable Frequency Drives (VFDs), inverter welders, UPS systems, and LED lighting introduce non-linear loads that inject harmonic distortion into the grid. Without proper mitigation, power quality issues can lead to severe operational failures:
- Transformer & Cable Overheating: Harmonics cause excessive heat in transformer windings and conductors, leading to premature insulation breakdown.
- Neutral Conductor Current Leakage: 3rd-order harmonics (triplen harmonics) accumulate on the neutral wire, creating severe overheating and potential fire hazards.
- Damage to Sensitive Electronics: Voltage Sags, Swells, and Transients can disrupt or destroy PLC controllers, servers, and medical instrumentation.
- Nuisance Circuit Breaker Tripping: Waveform distortion alters protection relay responses, causing unexpected circuit breaker trips.
Measurement Parameters & International Compliance Standards
Power quality audits conducted by PT Sentra Elektrikal Prima measure all critical electrical parameters in strict accordance with global benchmarks:
- Measurement Parameters: Harmonic Distortion for Current & Voltage (THDi & THDv), Voltage Sag / Swell, Transients, Phase Imbalance (Unbalance), Voltage Flicker, Power Factor, and Frequency fluctuations.
- International Compliance Standards: Our auditing procedures fully comply with IEEE 519-2022 (Standard Requirements for Harmonic Control in Electric Power Systems) and IEC 61000-4-30 Class A.
- High-Precision Calibration Equipment: We utilize industry-standard, fully calibrated Power Quality Analyzers capable of capturing high-speed transient events.
Engineering Approach: Total Harmonic Distortion (THD) Calculation
Demonstrating our commitment to technical depth, harmonic distortion evaluations are calculated using precise mathematical formulas to determine the total harmonic percentage relative to the fundamental frequency:
THD = √( ∑n=2∞ In2 ) / I1 × 100%
Formula Parameter Breakdown:
- THD = Percentage of Total Harmonic Distortion.
- I1 = RMS current value of the fundamental frequency component (50 Hz).
- In = RMS current value of the n-th harmonic component (n = 2, 3, 4, ...).
These calculations provide the foundation for PT Sentra Elektrikal Prima engineers to determine whether your facility requires Passive Harmonic Filters or Active Harmonic Filters (AHF).
Audit Deliverables & Technical Reports
At the conclusion of the electrical audit, you will receive a comprehensive engineering report that includes:
- Electrical Waveform Analysis: Mapping of real-time current/voltage waveforms and harmonic order spectra up to the 50th order.
- Energy Efficiency Calculations: Analysis of power losses resulting from poor power factor and harmonic distortion.
- Mitigation Design Solutions: Customized technical recommendations, including precise sizing and engineering specifications for Active Harmonic Filters (AHF) or Detuned Reactors.
