Manufacturing facilities running variable frequency drives (VFDs), large motors and other non-linear loads are the classic source of harmonic distortion, and a power quality analysis specifically measures this alongside power factor and voltage stability — issues that don’t show up as an obviously higher electricity bill the way a lighting or HVAC inefficiency might, but silently increase equipment wear, trigger DISCOM penalties, and reduce effective capacity of electrical infrastructure. IEEE 519 and the Indian standard IS 13779 set recommended limits on harmonic distortion for industrial installations, and Manesar’s dense concentration of automotive and auto-component manufacturing (a sector especially reliant on VFD-driven production equipment) makes power quality issues a common, if under-diagnosed, finding in the area’s industrial facilities. At a manufacturing company in Manesar, Haryana, Elion’s power quality analysis measured harmonic distortion levels against IEEE 519/IS 13779 limits, power factor against the DISCOM penalty threshold, and voltage stability across the facility’s electrical distribution.
Because power quality problems compound over time — degrading equipment life and increasing maintenance costs gradually rather than causing a single dramatic failure — facilities often don’t realize the issue exists until a power quality analysis specifically looks for it, unlike more visible problems like an obviously failing motor or a tripped breaker. This case study covers the specific findings from the Manesar facility’s power quality analysis and the corrective priorities recommended.
VFD-heavy manufacturing (common in Manesar’s automotive/auto-component sector) commonly generates harmonic distortion, checked against IEEE 519/IS 13779 limits. Power quality issues degrade equipment gradually rather than causing dramatic failure, which is why they often go undiagnosed without a dedicated analysis.

Harmonic Analysis and its Significance
Harmonic analysis is an essential part of power quality analysis. Harmonics are unwanted electrical frequencies that can distort the voltage and current waveforms. They can cause overheating, increased losses, and reduced efficiency in electrical equipment.
During the power quality analysis, Team Elion conducted a detailed harmonic analysis to identify any harmonic distortion in the electrical system. The analysis revealed the presence of significant harmonic distortion, which was contributing to the equipment failures and reduced efficiency.
Challenges Faced during the Power Audit
During the power audit and analysis process, Team Elion faced several challenges. One of the main challenges was accessing the necessary data from the manufacturing company. Some of the equipment did not have built-in power monitoring capabilities, making it difficult to collect accurate data.
To overcome this challenge, Team Elion installed temporary power monitoring equipment on the critical equipment to collect the required data. This allowed them to obtain accurate measurements and conduct a comprehensive power quality analysis.
Recommendations for Improving Power Quality
Based on the findings of the power quality analysis, Team Elion made several recommendations for improving power quality at the manufacturing company in Manaser. These recommendations included installing voltage stabilizers to address voltage fluctuations, implementing harmonic filters to reduce harmonic distortion, and conducting regular maintenance and monitoring of the electrical system.
Implementing these recommendations would help improve power quality at the manufacturing company, leading to reduced equipment failures, increased productivity, and improved profitability.

FAQs
Q1: Why do manufacturing facilities with VFDs commonly have power quality issues?
Variable Frequency Drives (VFDs) improve motor efficiency and process control, but they are also non-linear electrical loads that can introduce harmonic distortion into the power system. When large numbers of VFDs operate simultaneously without appropriate mitigation, harmonics may affect transformers, cables, switchgear, capacitor banks, generators, and sensitive electronic equipment. Other common industrial sources of power quality issues include UPS systems, rectifiers, welders, induction furnaces, and switched-mode power supplies. A power quality analysis identifies these disturbances and evaluates whether mitigation measures such as harmonic filters or system modifications are required.
Q2: What standards govern acceptable harmonic distortion in India?
Power quality assessments in India are generally carried out with reference to:
- IEEE 519 – Recommended Practice and Requirements for Harmonic Control in Electric Power Systems, which is widely used internationally for evaluating harmonic distortion.
- Central Electricity Authority (CEA) Regulations, where applicable.
- Relevant Bureau of Indian Standards (BIS) specifications and utility requirements.
- Applicable provisions of the National Electrical Code (NEC India) and equipment manufacturers’ recommendations.
Acceptable harmonic levels depend on the system voltage, network characteristics, and the point of common coupling (PCC). A professional analysis compares measured values against the appropriate applicable criteria.
Q3: How does poor power quality affect equipment beyond the electricity bill?
Poor power quality can have consequences well beyond increased energy costs, including:
- Premature failure of motors and transformers.
- Overheating of cables, switchgear, and neutral conductors.
- Reduced life of capacitor banks.
- Nuisance tripping of protective devices.
- Malfunction of PLCs, VFDs, and automation systems.
- Unexpected equipment shutdowns.
- Reduced production reliability and increased maintenance costs.
- Lower equipment efficiency and reduced operational life.
Identifying these issues early helps improve reliability, reduce downtime, and extend equipment life.
Q4: Why is power quality analysis especially relevant in Manesar’s industrial area?
Manesar is home to a large concentration of automotive, engineering, electronics, pharmaceutical, FMCG, and precision manufacturing industries, many of which rely heavily on automation, robotics, CNC machines, VFDs, welding equipment, and other non-linear electrical loads. These facilities often have complex electrical networks with sensitive production equipment, making them more susceptible to harmonic distortion, voltage fluctuations, imbalance, and transient disturbances. A power quality analysis helps ensure reliable operation, minimise production interruptions, and support efficient operation of critical industrial processes.
Q5: How is power quality analysis different from a standard electrical safety audit?
Although both assessments examine electrical systems, they have different objectives:
- Electrical Safety Audit: Focuses on compliance with electrical safety requirements, identifying hazards such as electric shock, fire risks, inadequate earthing, overloaded circuits, improper protection, unsafe installations, and maintenance deficiencies.
- Power Quality Analysis: Evaluates the quality of electrical supply by measuring parameters such as harmonic distortion, voltage fluctuations, voltage imbalance, flicker, transients, power factor, frequency variation, and demand profiles to improve equipment performance and system reliability.
Many industrial facilities perform both assessments because electrical safety and power quality address complementary aspects of electrical system performance.
