Power Quality Analyzer Testing
High-Precision Solutions for Power Quality Analyzer Testing
The quality of electrical energy supplied to consumers is one of the key factors for the performance and durability of electronic equipment. To ensure that distortion levels, imbalance, and other parameters remain within acceptable limits, the use of power quality analyzers—devices responsible for monitoring and analyzing energy quality—is essential.
The reliability of these analyzers directly depends on the accuracy with which they are tested and calibrated. Therefore, it is crucial to use equipment capable of generating complex, controlled signals with a high degree of fidelity. This is where Conprove stands out as the ideal partner for companies, laboratories, and research centers, offering state-of-the-art universal testers specially developed to validate and calibrate analyzers safely and accurately.
The Importance of Testing Power Quality Analyzers
Power quality analyzers are designed to measure and record parameters such as:
- Total Harmonic Distortion (THD)
- Flicker
- Voltage unbalance
- Frequency oscillations
- Transients
- Voltage sags and interruptions
- Harmonic and interharmonic content
These parameters are essential for identifying disturbances that may compromise the performance of electrical installations or damage sensitive equipment. To ensure reliable analysis, analyzers must undergo testing with controlled reference signals that simulate real-world grid conditions.
Conprove Solutions for Analyzer Testing
The CE-6707 and CE-6710 universal testers developed by Conprove offer exceptional precision and flexibility in signal generation. They are controlled via the CTC – Conprove Test Center, a software platform that integrates all Conprove equipment features, providing a user-friendly interface and advanced graphical analysis tools.
Key features for analyzer testing include:
- Signal generation with harmonic and interharmonic components: up to the 50th order, at 50 Hz or 60 Hz;
- Arbitrary waveform creation: sine, square, triangular, or custom shapes;
- Import of real oscillographs: faithful reproduction of COMTRADE and ATP files, allowing simulation of real disturbances;
- Definition of signals using symmetrical components: useful for voltage and current unbalance studies;
- Automated testing: full test sequences with report generation.
