Power quality analysers are essential tools for measuring electric power signals, ensuring the operation of electrical power systems in Hong Kong are working within optimal parameters. This is important as electrical equipment will not work to capacity or malfunction without the right electrical power. RS partners with major electrical test and power measurement equipment manufacturers, including Fluke, Chauvin Arnoux, Keysight, including the RS PRO brand, all recognised for their expertise in delivering performance within the industry. Our range includes calibrated power quality analysers with full calibration RSCAL certification.

Power quality analysers are multi-function meters that measure and test various electrical signals such as direct current, alternating current, AC-voltage, DC-voltage, harmonics and much more depending on the model. The data can then be logged and analysed with the software supplied with the power quality analyser helping you to avoid costly problems such as:

- Electrical equipment resets.
- Data errors.
- Equipment failure.
- Circuit board failures.
- Power quality supply issues.
- Software corruption.
- Electrical system overheating.

## **Types of Power Quality Analysers (PQA) Available**

Power quality analysers (PQAs) come in various configurations to suit different measurement needs.

### **Portable, Handheld, Desktop**

Power quality analysers are available in portable, handheld, and desktop models. Portable and handheld devices offer mobility for field measurements, while desktop models are suitable for stationary setups requiring extensive data analysis.

### **Mains Power or Battery Operated**

Some power quality analysers operate on mains power, making them ideal for continuous, long-term monitoring in fixed installations. Battery-operated models provide flexibility for temporary or remote measurements without the need for external power sources.

### **Calibrated (with Certification)**

Many PQAs come pre-calibrated with certification, ensuring accurate and reliable measurements. For instance, the PCE-GPA 62-ICA includes an ISO calibration certificate, meeting international standards.

### **Measurement Standards**

Power quality analysers adhere to various measurement standards, such as IEC 61000-4-30, ensuring compliance with international norms for power quality assessments.

### **Various Interface Options (Ethernet, LAN, USB, RS232, GPIB)**

Modern power quality analysers offer multiple interface options like Ethernet, LAN, USB, RS232, and GPIB, facilitating seamless data transfer and integration with other systems for comprehensive analysis.

## **Display Types**

Power quality analysers feature various display technologies to enhance user experience and data interpretation.

- **Backlit:** Backlit displays illuminate the screen from behind, improving visibility in low-light conditions.
- **LCD:** Liquid Crystal Displays (LCDs) use liquid crystals to modulate light, offering energy efficiency and clarity.
- **Colour:** Colour displays provide a full spectrum of colours, aiding in the differentiation of data points and trends.
- **Graphics:** Graphics-capable displays can render complex waveforms and charts, facilitating detailed analysis.
- **TFT:** Thin-Film Transistor (TFT) displays use individual transistors for each pixel, resulting in sharper images and faster response times.

## **Measurement Types**

Power quality analysers are essential tools for assessing various electrical parameters to ensure system efficiency and reliability.

- **AC Current, Voltage, Wattage:** Power quality analysers monitor fundamental parameters like AC current, voltage, and wattage, providing real-time data on power consumption and system performance.
- **Current, Energy, Flicker, Frequency:** They also monitor energy usage, detect flicker (rapid voltage fluctuations affecting lighting), and measure frequency variations, which are crucial for maintaining power quality standards.
- **Harmonic, Impedance, Inrush, Inverter Efficiency:** Advanced power quality analysers analyse harmonic distortion, assess impedance, capture inrush currents during equipment startup, and evaluate inverter efficiency, aiding in the diagnosis of electrical issues and optimization of system operations.

## **How Power Quality Analysers Work?**

Power quality analysers are meters designed to assess the quality of electrical power in systems. They function by measuring and analysing various electrical parameters to detect disturbances that could affect equipment performance and longevity.

Here are their key components and measurement techniques:

- **Voltage and current sensing:** Power quality analysers use sensors such as current transformers (CTs) and voltage dividers to monitor voltage and current waveforms. These sensors provide real-time data on the electrical signals within the system.
- **Signal processing:** The captured signals are processed using techniques like Fourier analysis to identify harmonic distortions and other waveform anomalies. This analysis helps in understanding the frequency components of the signals.
- **Data display and analysis:** Processed data is displayed on the analyser's interface, often featuring graphical representations like waveforms and histograms. This visual data aids in diagnosing power quality issues such as sags, swells, harmonics, and flicker.

## **Power Quality Analyser Applications**

Power quality analysers are essential tools across various industries, ensuring optimal performance, energy efficiency, and compliance with regulations.

### **Manufacturing**

In manufacturing, power quality analysers monitor voltage stability, harmonics, and frequency variations to prevent equipment malfunctions and downtime. For instance, in textile manufacturing, harmonic distortions from variable frequency drives (VFDs) can lead to overheating and reduced equipment lifespan. Identifying and mitigating these issues enhances operational efficiency and reduces maintenance costs.

### **Utilities**

Utilities use power quality analysers to assess grid stability, detect faults, and ensure power quality standards are met. This proactive monitoring helps maintain a reliable power supply and ensures adherence to regulatory requirements.

### **Energy Management**

In energy management, power quality analysers aid in energy audits by identifying inefficiencies, such as poor power factor or unbalanced loads. Addressing these issues leads to reduced energy consumption, lower costs, and compliance with environmental standards.

## **How to Choose the Right Power Quality Analysers?**

Selecting the appropriate power quality analyser involves evaluating several key factors to ensure it meets your specific measurement needs.

- **Measurement Accuracy:** Select a power quality analyser that complies with international standards, such as IEC 61000-4-30. Consider models with Class A or Class S accuracy for precise measurements of voltage, current, harmonics, and other parameters.
- **Data Logging Capabilities:** Opt for analysers with robust data logging features, allowing for extended monitoring periods. This is crucial for identifying intermittent power quality issues and generating comprehensive reports.
- **User Interface:** A user-friendly interface enhances efficiency. Look for devices with intuitive touchscreens, clear visualisations, and easy navigation to facilitate quick data interpretation and analysis.
- **Compatibility with Power Systems:** Ensure the power quality analyser supports the voltage and current ranges specific to your application. Additionally, verify compatibility with various power systems, including single-phase and 3-phase configurations, to accommodate diverse testing environments.
