PARMA

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.

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
