Measurement and evaluation of power quality
For the reliable and safe operation of electrical systems, currents and especially voltages must fulfil certain specified quality characteristics. For this purpose, on the one hand, the energy supplier must ensure a voltage quality according to DIN EN 50160 at the customer's grid connection point. On the other hand, the customer himself should regularly check both the voltage quality within his installation to protect his equipment and the grid perturbations emanating from it, which in turn pollute the upstream grid of the energy supplier. After all, reduced power quality leads to various problems (EMC interference, increased heating up to destruction, etc.), operational failures and associated high costs. Therefore, have the power quality in your company checked regularly, especially before installing a new system, in order to prevent electrical problems.
Similar to checking the water content of the brake fluid in a car, a measurement does not cost much, although a malfunction can have serious consequences.
