Power Quality Analyzers

Our analyzers measure and analyze power quality in real-time. They conform with IEC 61000-4-30 and IEEE 519-2019 standards for power quality monitoring.

Many utility customers experience unplanned production stoppages, which are often mistakenly attributed to power loss or service interruption. However, many stoppages are actually caused by voltage sags.

Our analyzers serve as a powerful diagnostic tool, providing precise measurement of events such as voltage sags, swells, harmonic voltages, currents or flicker. By analyzing this data, the root cause of unplanned production interruptions can be identified.

Frequent Ask Questions

What is power quality monitoring?

Power quality monitoring is the process of measuring and analyzing the electrical characteristics of a power system, such as voltage, current, frequency, andharmonics, to identify and diagnose power quality issues.  

IEC 61000-4

IEC 61000-4 is an international standard from the IEC which defines procedures for testing and evaluating the immunity of electrical and electronic products to electromagnetic interference (EMI).

IEC 61000-4-30 sets the requirements for measuring and assessing power quality characteristics. Part 4-30 set the testing and measurement techniques like the measurement method, accuracy and time aggregation for analyzers to record the different parameters.

What are consequences of poor power quality?

Poor power quality can lead to a range of problems, including automatic resets, data errors, equipment failure, circuit board failure, memory loss, power supply issues, UPS alarms, and overheating of electrical equipment. These issues can have a significant impact on your operations and should be prevented by ensuring high-quality power supply.
