PARMA

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

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

Scope of application · measurement of electrical energy parameters in three-phase or single-phase current networks with their subsequent transmission to the upper level of the AIS · the device of the lower level in the AIS at the facilities of generation, conversion, transmission and distribution of electricity

Appointment. Scope of application · continuous monitoring of the 220 V network · identification of problems with power supply in a single apartment, company or HOA · conducting inspections and finding out the source of deterioration in the quality of electricity in apartment buildings, in HOA, in business centers · formation of an expert base when resolving (in court or pre-trial) conflicts between energy marketing organizations and consumers - individuals · justification of the reasons for the failure of expensive household appliances from consumers

Purpose and functions: · Receiving and transmitting the exact time to one or more subscribers · Synchronization of equipment operation at the exact time · Synchronization of subscribers by time within both one and several objects, i.e. creation of a hierarchy of subscriber systems tied to a single astronomical time at sufficiently large distances · Retransmission of accurate time signals to the shielded premises of objects (basements, mines, etc.) The PARMA RV9.01 system consists of a GPS receiver and a set (from 1 to 4) repeaters.

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

Scope of application · operational maintenance of relay protection circuits and power circuits of electrical installations · phasing during adjustment of differential protection, connection of current and voltage transformers, electric motors · control of the correct phasing of the connection accounting circuits · removal of the volt-ampere characteristic and measurement of angles · monitoring of single- and three-phase circuits in power supply cabinets

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.

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)

PARMA TENSOR-2 (AC bridge) is designed for automatic measurements of: · capacitance and tangent of the dielectric loss angle of high-voltage insulation of capacitors, inputs, transformers using an external high-voltage capacitor, both in laboratory and in the "field" conditions · effective values of the first harmonic of the current and voltage of the industrial frequency · the angle of phase shift between the signals supplied to the inputs of the device · network frequencies * Measurements can be carried out according to the "straight" and "inverse" (inverted) scheme. * Allocates the vector of the influence current, which makes it possible to dispense with the phase regulator of the test voltage source or devices for compensating the influence current.
