ACCURATE TIME SIGNAL TRANSMISSION SYSTEM PARMA RV9.01

A series of modern intelligent relay protection, automation and alarm units PARMA IED-EP+ is designed for use in networks with a voltage from 6 to 750 kV

PARMA UACHR 12 is designed to eliminate the shortage of active power in the network by automatically turning off consumers when frequency decreases, followed by automatic re-activation of previously disconnected consumers when frequency is restored, as well as to eliminate the shortage of reactive power in the network by disconnecting consumers when voltage decreases, followed by automatic re-activation of previously disconnected consumers when voltage is restored. PARMA UACHR 12 can perform the functions of dividing automation, be used at power plants and substations of power systems, as well as a device for local emergency automation of 0.4 kV networks as part of an automatic load control system. PARMA UACHR 12 is the first microprocessor-based frequency unloading device in Russia that has received a certificate of compliance with the requirements of the standard of the organization of JSC "SO UES" STO 59012820.29.020.003-2016 "Relay protection and automation. Automatic emergency management of power systems modes. Microprocessor devices for automatic frequency unloading. Norms and requirements" No. NC11.SO.RU.0417.0001 One PARMA UACHR 12 device can replace a typical ACR circuit made on microelectronic or electromechanical relays of the RSG-11 type; RF-1, RF-2 and URCH-ZM

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 The relay "PARMA Rh-2" is optimally suited: • for retrofit of cells to replace outdated relays with a switch of any type, including when using a deshunt circuit • as an alternative to modern microprocessor protections with excessive functionality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

Appointment For use in measuring: · capacitance and tangent of the dielectric loss angle of high-voltage insulation (capacitors, inputs, transformers, insulators) · characteristics of partial discharges of liquid dielectrics in laboratory and field conditions, complete with an insulation parameter meter (for example, PARMA TENSOR-2)

Purpose and functions: · Transmission of accurate time signals via the IRIG-B protocol to remote subscribers via optical communication channels up to 1 km · Retransmission of signals to several channels, thereby ensuring the connection of one to eight devices to one time server

USVI(PMU) functionality: · Supports computing and data transmission in on-line mode via the C37.118-2011 protocol · have two built-in Ethernet interfaces for connecting to the LAN of the installation object · save data for later access via FTP – off-line mode

Allows to significantly simplify the procedure for checking, configuring and demonstrating microprocessor relay protection units. The use of the stand makes it possible to significantly simplify the procedure of demonstration, verification and configuration of microprocessor relay protection units. The stand allows to check such protections as MTZ and OZZ, including directional, ZMN, ZPN, ZOF. With the help of the stand, you can easily check the automation functions of the RZA units, for example, URV, APV, AVR, etc.

UVI/PMU functionality · supports calculation and data transmission in on-line mode via the C37.118-2011 protocol · has 2 built-in Ethernet interfaces for connecting to the LAN of the installation object · saves data for later access via FTP – off-line mode · connection of up to 9 connections to one device with the possibility of distributed installation across the facility
