Megger Power Quality Analysers

About Megger Power Quality Analysers

Megger power quality analysers are instruments designed to assess and monitor various parameters of electrical power systems, ensuring optimal performance and compliance with industry standards.

Measurements and Functions

These analysers evaluate several critical aspects of power quality, including:

• Voltage and Current: Monitoring RMS values to detect over-voltages, under-voltages, and current imbalances.
• Harmonics: Identifying harmonic distortions that can affect equipment performance.
• Flicker: Measuring voltage fluctuations that may cause noticeable light intensity variations.
• Unbalance: Detecting asymmetries in three-phase systems that can lead to inefficiencies.
• Frequency: Ensuring the system operates at the correct frequency, typically 50 Hz or 60 Hz.
• Power and Energy: Calculating active, reactive, and apparent power, as well as energy consumption.
• Transients and Events: Recording sudden changes or disturbances in the power supply.

Operation

Megger's power quality analysers, such as the MPQ1000 and MPQ2000, are designed for user-friendly operation:

• Data Acquisition: Equipped with multiple channels to simultaneously capture voltage and current data across all phases.
• Real-Time Analysis: Features like scope mode and digital voltmeter (DVM) mode allow users to view real-time waveforms, demand data, phase angles, and more.
• Recording and Storage: Data is stored on expandable memory cards, facilitating extended recording periods.
• Connectivity: Interfaces such as USB, Ethernet, and wireless options enable easy data transfer and remote monitoring.
• Software Integration: Comprehensive analysis software assists in evaluating recorded data, generating reports, and ensuring compliance with standards like IEC61000-4-30 Class A.

Applications

These analysers are essential in various settings:

• Industrial Facilities: Monitoring and maintaining power quality to prevent equipment malfunctions and downtime.
• Commercial Buildings: Ensuring efficient operation of electrical systems and compliance with regulatory standards.
• Utilities: Assessing power distribution networks to identify and rectify quality issues.
• Renewable Energy Installations: Evaluating the integration of renewable sources into the grid to maintain stability.
