Since the start of Germany’s energy transition, voltage quality in distribution networks—commonly referred to as power quality—has become increasingly important. Ideally, voltage in the grid should follow a pure sinusoidal waveform, defined by its amplitude, frequency, and shape.
However, due to changing grid conditions and the growing use of non-linear electrical loads and generators—such as frequency converters, UPS systems, energy-saving lamps, PCs, copiers, and filter circuits—these ideal conditions are frequently disrupted. The result is distorted current and voltage waveforms, degrading power quality and potentially affecting other users connected to the grid.
Overheating of motors
Unexpected shutdowns caused by residual current devices or blown fuses
Flickering of fluorescent lights and display screens
Failure of electronic ballasts
Disruption of ripple control signal transmission
Damage or false alarms in wireless smoke detectors
Increased reactive power demand, resulting in higher electricity bills
Poor power quality places a burden on consumers, and in the worst-case scenario, can pose risks to people and property. As early as 2007, a study estimated that grid-related phenomena caused economic losses of €157 billion annually, a number that has continued to rise. While not a new issue, power quality has gained renewed attention due to our increasingly technologically advanced and sensitive electrical environments.
Power disturbances are monitored and managed based on IEC 61000-xx electromagnetic compatibility (EMC) standards.
Continuous monitoring of the power grid helps identify disturbances at an early stage and prevent system failures.
With the help of advanced current measurement instruments, FaTeng Electric’s specialized equipment and analytical platform can reliably and permanently record and assess all common disturbance parameters and voltage events—such as harmonics, frequency deviations, and flicker.
Built-in high-resolution PQEasy Reports allow experts to instantly visualize grid issues without expensive third-party software.
Differential current measurement enables early detection of insulation faults.
Threshold alarms can be set to automatically trigger alerts when critical limits are exceeded.
This enables the proactive planning and implementation of countermeasures, helping avoid costly system downtimes and improving long-term power reliability and safety.
