Do you worry about the power quality in your distribution network? Do you wonder if the voltage along a line remains within the allowed tolerance range? Do you ask yourself what the impact of installing new power system equipment in your network will have on the power quality? As well as power system simulations, we can give you answers to these questions and many more through a measurement campaign. In some cases, a measurement campaign is the perfect supplement to a grid study conducted by us. Our services range from simple measurements of electrical quantities (e.g. frequency, voltage, current, power, etc.) to more costly measurements, like power quality, at multiple locations on a power network.

Power Quality

Power quality is a very general term summing up the effects of several more specific quantities such as frequency, voltage amplitude, power interruptions, flicker, harmonics, and phase unbalances. Unacceptable power quality can lead to grid disturbances and damage to both utility and customer owned equipment. In order to precisely assess power quality it is recommended to take measurements over a longer period of time (i.e. over several months). The measured power quality values can be compared against power quality standards such as EN 50160.

Power quality analyzers come in various accuracy classes. The devices with the highest level of accuracy are certified for class A (IEC Norm 61000-4-30). Measurements which have lower accuracy demands are suited for class S measurement devices or devices without a certificate.

Whether you want to measure power quality on various points of a transmission, distribution, or industrial network or the emissions of a new consumer or generator site, together we will find the optimal solution and the best-suited device for the job.

Voltage Angle Measurement

Phasor Measurement Units (PMUs) are used to measure voltages and currents along with their corresponding phase angles and offer a high temporal resolution. Through the synchronization of all PMUs to GPS, the phase shift between measured parameters can be determined.

Using this method, it can be precisely determined how voltage angle and amplitude change along a power line. Voltage angle can be the limiting factor for system stability on long transmission lines, which is why it is of utmost importance to measure this quantity with high precision.

We look forward to advising you on the ideal use of PMUs in your network and carrying out a measurement campaign tailored to your needs!

Efficient Measurements around the Globe

All measuring devices used by Energynautics can be equipped with a router with a SIM card to establish an internet connection. Doing so we can continuously read and evaluate measured data coming from anywhere around the world. This also reduces the necessary frequency in which our employees need to travel to the project site. With a remote internet connection this is only necessary for installation of the devices at project start and removal of the equipment at project completion, regardless of project duration. Real-time measurement information is available to you through the continuous monitoring of all desired parameters.
