Harmonic compliance surveys are conducted to ensure that the levels of your harmonics do not contribute to problems in the Public Electricity Supply that could cause problems for other users. Harmonics limits are specified in EN50160, G5/4-1, G5/5 and IEC standards that we use to issue a harmonic compliance report for you installation. Data logging equipment used to monitor the electrical supply complies with EN61000-4-30 as defined in the latest edition of the power quality measurements and methods standard.
