Power Quality Analyzer Model 8230 656.3.7 MonitoringThe EN50160 standard defines limiting values and permissible variations of thevoltage quality for the European Community. It defines which parameters arerelevant, and how are they measured. Continuous or random sampling controlof the voltage quality provides the supplier of electric energy with a reliable basiswhen dealing with network problems, and it contributes to quality assurance.The purpose of the EN50160 standard “Voltage characteristics of electricity sup-plied by public distribution systems” is to specify the characteristics of the supplyvoltage with regard to the course of the curve, the voltage level, the frequency andsymmetry of the three phase-network at the interconnecting point to the customer.The goal is to determine limiting values for regular operating conditions.However, facility defects may lead to major disturbances in the electricity distributionsupply network. Accordingly, the standard establishes these values as limitingvalues, which are not allowed to be exceeded on the high or low side during 95%of the controlled period, typically one week.Figure 6-12Configure and start an EN50160 test of line quality. It is recommended that a brieftest of 10 minutes or shorter be done first, to verify the connections and param-eters of the test are correct. Only then should the 1-week test be done.If neither of the voltage profiles are chosen, a field appears to enter the nominalvoltage. The frequency is not asked for, since it will be asked for when the testresult is downloaded.Follow the instructions in the dialog box to set up and run this special test.
