It is becoming increasingly important to monitor the quality of the power supplied to an installation as defined by standards such as EN50160.

SHM supply a range of easy-to-use high-performance electricity meters that not only measure power and energy consumption but also parameters such as power factor, frequency, total harmonic distortion (THD) and harmonic content.
