Power Quality Measurement & Digital Fault Recording
In view of the growing number of factors with a disturbing influence on power systems and the ever increasing sensitivity of devices and installations on the consumer side, simple monitoring criteria such as undervoltage or overcurrent are no longer adequate. Reliable registration of all the relevant processes within the electrical power system calls for constant observation of a wide variety of derived parameters, such as individual harmonic content, system unbalance and interharmonics, and the swift identification of even slight deviations from the norm.
