Power Quality & Performance Testing

Power That Just "Turns On"
Isn't Enough.

Poor power quality damages equipment, inflates energy bills, and causes hidden downtime. We fix harmonics, power factor, and validate system performance before full operation.

The Impact of Poor Power Quality

Hidden Problems That Cost Your Business

Power quality issues often go unnoticed until damage has already occurred — and the impact is far more expensive than the cost of the fix.

3–8%
Wasted Energy
Low power factor increases reactive current, meaning higher electricity bills with no increase in output.
40%
Shortened Equipment Life
Excess harmonics cause overheating in motors, transformers, and conductors — significantly shortening their lifespan.
Void
Voided Equipment Warranty
Many OEMs require power quality within certain limits. Violations can void warranty claims on expensive equipment.
Trip
Unexpected Downtime
Harmonics and voltage transients trigger nuisance tripping in protection systems — causing unplanned production shutdowns.

Four Pillars of Power Quality We Handle

Every solution is engineered for real field conditions — not laboratory theory.

Active Harmonic Filter (AHF) – Elecnova

An AHF detects and injects a compensating current that's out of phase with the harmonics — eliminating total harmonic distortion (THD) in real time. A must-have for facilities with many variable speed drives, UPS units, rectifiers, or other non-linear loads.

THD corrected to below 5% (IEEE 519 standard)
Simultaneous compensation up to the 50th order
Real-time response with no switching delay

Static Var Generator (SVG) – Real-Time Power Factor Correction

Unlike conventional capacitor banks, SVG uses power electronics technology to compensate reactive power dynamically and precisely — with no resonance risk and no switching delay. Ideal for rapidly fluctuating loads.

Dynamic compensation that follows real-time load fluctuation
No resonance risk like with capacitor banks
Reduces kVAR charges and PLN penalties

Load Bank Testing – Documented Performance Validation

A load bank test validates a genset's ability to carry actual load at various levels — from no-load to 110% overload. It's the only way to prove the system is truly ready before it's used for a critical load.

Full Commissioning – System Ready for Operation

Commissioning isn't just "switch it on and see what happens." It's a systematic process of verifying every component, every protection function, and every sequencing step — with complete documentation that can be audited anytime.

Our Methodology

Standardized Process, Verified Results

Every power quality and commissioning job follows the same methodology — structured and auditable.

1

Power Quality Assessment

Measuring existing conditions using a power quality analyzer — identifying the current system's harmonics level, power factor, voltage unbalance, and transients.

Deliverable: PQ Assessment Report
2

Engineering & Sizing

Calculating the required AHF/SVG capacity based on actual measurement data — not estimates — to ensure a targeted, cost-efficient solution.

Deliverable: Engineering Calculation, Single Line Diagram
3

Installation & Integration

Installing the AHF/SVG, configuring parameters, and integrating with the existing monitoring system by certified technicians using a zero-disruption approach to ongoing operations.

Deliverable: Installation Record
4

Verification & Final Report

Post-installation measurement to verify the improvements achieved. A before-after comparison report is prepared as proof of performance, usable for energy audits or insurance purposes.

Deliverable: Before-After Report, Final Commissioning Certificate

From Our Clients

Power Quality Proven to Improve

★★★★★

"After the Elecnova AHF was installed, our production motors stopped overheating. THD dropped from 31% to 4.7%. The energy savings we recorded in 6 months were already more than enough to cover the investment cost."

Energy Manager · Plastics Manufacturing, Tangerang
★★★★★

"The load bank test Jerbindo performed before commissioning found a problem with the genset's AVR that had gone undetected. Fortunately it was found before the system was used for our hospital's critical loads."

W
Wahyu N.
Technical Director · Private Hospital, Semarang
★★★★★

"Our PLN power factor penalty disappeared completely after the Elecnova SVG was installed. Power factor rose from 0.74 to 0.99. The complete commissioning report Jerbindo provided was also a huge help for our company's energy audit report."

FAQ

Frequently Asked Questions About Power Quality

We explain things technically and honestly — without unnecessary jargon.

A capacitor bank is a passive solution that can only compensate reactive power at the fundamental frequency (50 Hz) and can cause resonance with harmonics. An AHF is an active solution that compensates reactive power while eliminating harmonics in real time — far more effective for modern non-linear loads. An SVG is an active solution specifically for reactive power compensation, with no capacitor bank resonance risk.
It's not required by regulation, but it's highly recommended — especially for critical facilities like hospitals, data centers, or production facilities. A load bank test is the only way to verify genset performance under actual load before it's used for a real load. Many backup power system failures happen because there was no adequate load test before commissioning.
ROI varies widely depending on existing conditions, electricity tariffs, and system scale. Generally, savings come from: eliminating PLN penalties, reduced energy costs (5–15%), reduced equipment maintenance costs, and extended equipment life. A typical payback period for SVG is 12–24 months, and for AHF 18–36 months depending on the existing harmonics level.
Yes, measuring existing conditions is the first step we take before recommending any solution. The measurement data determines the type and capacity of equipment needed — without it, sizing could be too large (wasted cost) or too small (ineffective solution). We provide power quality measurement services with a complete report.
