Power grid analysis
Is the quality of the power supply for your business indispensable and of utmost importance? Then you should not hesitate to perform a comprehensive mains analysis. It does not matter whether you consider a data center, an industrial plant or office workstations – our service technicians will analyze your network both at UPS-side and at the general supply side. We examine by measurements with your own equipment 3-phase low voltage power supply and track events and anomalies. Loss of quality in terms of network quality can be caused by switching operations by load changes or by non-linear loads.

Our Mains Analysis Service in Details:
Voltage/Current/Frequency
High interference components in power systems can lead to a shortfall in production. Using a V/C/F – Ana- lysis, we can analyse and recognize coarse interference components in power-supply systems. By determination of the crest factor we are able to work out an initial assessment of the power system with regard to its interference components.
Drops and Peaks
Drops and peaks in power systems can lead to failure of sensitive electronic equipment. Switched mode power supplies can be irreparably damaged. By means of this particular analysis, we can detect voltage drops and peaks, interruptions, power fluctuations and peak values. According to EN61000-4-30 the variations between half a cycle can be up to several seconds. In a 3-phase system the drop or peak begins when the voltage in one or more phases falls below or increases above a defined threshold. Dips and peaks are characterized by the duration, magnitude and time of occurrence. We record this and thereby we are able to locate sources of interference.
Harmonics
Harmonics are periodic distortions of the sinusoidal signal of voltage, current or power. Harmonics can cause overheating of transformers, conductors and motors. We record harmonic and inter-harmonics. A signal form is a combination of diverse sine waves having different frequencies and amounts. We determine the share of each of these components to the full signal.
Power / Energy
Our technicians can locate your energy consumption and provide guidance for optimization. The overloading of a transformer can be detected early. We detect apparent power, active power, reactive power, power factor and displacement power factor.
Flicker
The so-called flicker quantifies the number of lamps brightness variations caused by voltage fluctuations in power supply. A high-speed flicker can cause headache and indisposition. We record all necessary parameters using an algorithm according to the standard EN61000-4-15, and can locate the cause of the flickering.
Asymmetry
Voltage asymmetries cause extremely asymmetrical currents in motor stator windings and shorten generally engine life strong. We record and analyze your power system, identify potential asymmetries and make re- commendations to avoid this.
Transients
Transients are fast peaks in the voltage or current signal which may have such high energies that sensitive electronic devices be disturbed or damaged. Computer systems often run for no apparent reason a restart. We detect transients occurring by measurement and search for the root cause. Such measures may help to prevent interference with other users.
Inrush Currents
Inrush currents are so-called surge currents, known to occur when switching-on low-impedance load. Inrush currents can interfere with other devices in operation. High current peaks can cause unexpected release of isolating switches for example. We analyze the power quality during the occurrence of inrush currents and thereby we can make an evaluation of the interference of other devices.
