The devices are designed for: measurements and registration of the main indicators of the quality of electrical energy established by GOST 32144-2013 (GOST R 54149-2010) with registration of protocols according to GOST 33073-2014; measurements and registration of the main parameters of electrical energy in single-phase and three-phase electrical networks (including the effective values of voltages and currents with sinusoidal and distorted curves; active, reactive and full electrical power); measurements of parameters of secondary circuits (load capacity of measuring transformers and voltage drop) in electric energy metering systems and electric energy losses in power supply lines. functional test and verification of connection of meters of active and reactive power and energy, energy measuring converters of voltage, current at the places of their operation; functional test and verification of the connection of single-phase and three-phase electric energy meters without breaking current circuits to detect theft of electricity; measurements of electricity losses in the power supply line. The PKE-A energy tester provides registration with subsequent transfer to a personal computer (PC) of statistical data on the PKE: Values of the PCE according to GOST 30804.4.30 (GOST P 51317.4.30) and GOST 30804.4.7 (GOST P 51317.4.7) with a registration depth of 512 days; Values and durations of voltage dips and overvoltages; Values of the short-term dose of flicker; Parameters of the electrical network and vector diagrams with the depth of registration: - 24 hours for averaging time of 3 s, - 200 days for averaging time of 10 min. The program "Energy Monitoring ES" provides the formation of quality control protocols in the form of GOST 33073-2014.

The current relays of the PARMA Rh-2 series are designed to perform the functions of relay protection and automation of connections of 6 – 35 kV in networks with an isolated neutral. The current relays of the PARMA Rh-2 series combine the advantages of microprocessor protections and the simplicity of relay circuits on traditional electromechanical and electronic relays. The relay "PARMA Rh-2" is optimally suited: • for retrofit of cells to replace outdated relays with a switch of any type, including when using a deshunt circuit • as an alternative to modern microprocessor protections with excessive functionality • when creating and reconstructing RPA systems of power facilities in conditions of limited budget funds
