About the Service
Power Quality Analysis Services
Sachu Technologies provides Power Quality Analysis Services to measure electrical parameters and identify disturbances that may affect equipment performance, system reliability, and energy use. We support industrial plants, commercial buildings, hospitals, data centres, utilities, and manufacturing facilities across India.
What Is Power Quality Analysis?
Power quality analysis involves measuring and evaluating voltage, current, frequency, power factor, harmonics, and other electrical parameters. It helps identify abnormal conditions within an electrical distribution system.
Poor power quality may lead to equipment malfunction, unexpected shutdowns, excessive heating, nuisance tripping, data loss, reduced equipment life, and increased electrical losses. However, these problems may occur only during certain operating conditions. Therefore, continuous monitoring is often required to capture them.
Our specialists connect a suitable power quality analyser at selected measurement points. The instrument records electrical data during an agreed monitoring period. We then analyse the collected information and prepare a structured technical report.
Parameters We Measure
Depending on the inspection scope, our Power Quality Analysis Services may include measurement of:
- Phase-to-phase and phase-to-neutral voltage
- Phase current and neutral current
- Supply frequency
- Active power
- Reactive power
- Apparent power
- Power factor
- Maximum demand
- Voltage imbalance
- Current imbalance
- Voltage harmonics
- Current harmonics
- Total harmonic distortion
- Individual harmonic orders
- Voltage dips and swells
- Short-duration interruptions
- Transient events
- Inrush current
- Flicker and voltage fluctuations
- Load profile and energy consumption
Power Quality Problems We Investigate
Power quality monitoring can help investigate:
- Repeated tripping of circuit breakers
- Unexpected equipment shutdowns
- Voltage fluctuations
- Overheating of transformers and cables
- Excessive neutral current
- Poor power factor
- Capacitor-bank failures
- Motor and drive problems
- Lighting flicker
- Equipment malfunction
- Harmonic distortion
- Phase-load imbalance
- UPS and inverter-related disturbances
- Unexplained electrical losses
- Failure of sensitive electronic equipment
A recorded disturbance does not always confirm its exact source. System design, equipment specifications, operating conditions, load behaviour, and maintenance history must also be considered.
Our Approach
1. Assess
We understand the reported concerns, electrical system, connected loads, equipment behaviour, measurement objectives, and site operating conditions.
2. Plan
Suitable monitoring locations, parameters, instruments, recording intervals, and monitoring duration are selected based on the inspection requirements.
3. Monitor
A power quality analyser is installed at the agreed measurement point to record electrical parameters during representative operating conditions.
4. Analyze
Recorded data is reviewed to identify disturbances, harmonic levels, load variations, phase imbalance, power-factor concerns, and other abnormal conditions.
5. Report
A structured report is prepared with measurement data, graphs, event records, observations, and a summary of identified power quality conditions.
6. Recommend
Findings are presented to help the facility evaluate possible causes and determine appropriate corrective measures, further testing, or continued monitoring.
For a focused assessment of waveform distortion, facilities can also consider our Harmonic Study Services. An Power Quality Analysis can support a broader review of the electrical installation.
General information about electrical regulations and safety requirements is available from the Central Electricity Authority.
Frequently Asked Questions
Power quality analysis measures and evaluates electrical parameters to identify disturbances or conditions that may affect the reliable operation of electrical equipment.
It can help identify harmonics, voltage dips and swells, load imbalance, poor power factor, excessive neutral current, frequency variations, interruptions, and unusual load patterns.
Monitoring provides recorded data about electrical-system behaviour over time. This helps investigate intermittent issues that may not be visible during a short inspection.
The required duration depends on the reported issue, load cycle, process schedule, and monitoring objective. It may range from several hours to multiple days or longer.
A temporary shutdown may be required depending on the measurement location, panel design, access conditions, and site safety procedure. The requirement must be assessed before installation.
Not always. It identifies electrical events and abnormal patterns, but system design information, equipment history, operating conditions, and further testing may be needed to confirm the root cause.
Yes. Sachu Technologies provides power quality analysis and electrical monitoring services for industrial and commercial facilities across India.
