产品描述

Portable devices MPK2 are designed to measure power quality parameters by voltage at the points of installation of substation power quality measuring devices, monitoring and control systems of power quality parameters with saving of measurement results according to specified algorithms in time intervals counted by internal clocks of real astronomical time. Calculation of power quality parameters is carried out according to class A in accordance with GOST 30804.

4. 30-2013, GOST 32144-2013.

The device supports the IEC 61850-8-1 digital substation protocol (MMS). MPK2 is included in the State Register of SI of the Russian Federation No.

71684-18. Interverification interval is 10 years.
