It measures RMS netwrk values and all significant deviatins frm the nminal values by means f fast sampling f vltage and current signals. There is an ptin in MiQen Settings Studi sftware t select als the measurements based nly n psitive sequence fundamental wave, which des nt include harmnics measurements. This ptin can be fund under MiQen Settings menu. With this ptin included all crrespnding values are replaced by IEC Annex C measurements. This makes supervisin relay SR100 suitable fr acquisitin and validatin f fast changes in the netwrk. A built in micrcntrller calculates measured values (vltage, current, frequency, energy, pwer, pwer factr, THD phase angles, and deviatins) and sends these data ver a reliable CANpen cmmunicatin interface t the CAN master devices.
