Power quality with DEHN

Corporations, small businesses, private households – the supply of electrical energy is a basic necessity for everybody.

For power grids to operate reliably and seamlessly, the power quality, the quality of the voltage supply, must be right. Yet power supply grids are becoming increasingly susceptible to malfunctions. Above all, this is down to the increasing number of decentralised generating and non-linear consumption systems.

Also, the amount of sensitive electronic equipment is increasing. The steeply rising number of these non-linear loads, such as frequency converters, inverters, power supply units, LED street lights and also electric mobility, is resulting in considerable line harmonics.

The core business of a power supply company or power grid operator is to provide users with energy of the right quality - and to do so as reliably as possible. The basis for this is the use of power quality measuring equipment that provides useful information. DEHN has developed a multifunctional measuring and analysis device for precisely this requirement which measures to class A standard. With the extensive installation of DEHNrecord SD in a low-voltage system, simple and future-proof monitoring is enabled, disruptions and faults are identified promptly, and evidence is documented which is admissible in court in the event of damage.
Power quality monitoring as per EN 50160

DEHNrecord SD can be suitably configured through an integrated Web server or DEHNmonitor PQ.

EN 50160 - Voltage characteristics of electricity supplied by public electricity networks defines and specifies the key characteristics of supply voltage at the network connection point under normal operating conditions.

The characteristics of the supply voltage are defined for frequency, magnitude, waveform, and balance of the phase-to-phase voltages. During normal grid operation, load fluctuations, disturbances and faults such as short circuits lead to changes in the parameters. By measuring all relevant parameters, DEHNrecord SD enables simple and future-proof monitoring so that disruptions and faults are identified promptly.

DEHNrecord SD – an impressive device concept

Combining cleverly

The multifunctional DEHNrecord SD measuring and analysis device identifies malfunctions reliably in line with standards and beyond, and can be easily and quickly combined with lightning current and surge arresters at the perfect installation location for stationary measurements.
