PD-Unit – portable device for on-line monitoring of high-voltage equipment insulation


PD-Unit portable measuring device is used for on-line monitoring of the insulation condition.

  • The device does not have any screen or keyboard. All the controls are done from a smartphone or a tablet through a standard wireless communication interface.
  • In-built HF and UHF frequency sensors for PD measurement.
  • 4 types of external sensors can be connected to the device.
  • With PD-Unit partial discharges can be measured in the insulation of the switchgears, terminal and coupling joints of the cables, gas-insulated equipment (GIS), in high-voltage tank equipment - power transformers, switches, etc.

FDM – monitoring system for technical condition of asynchronous electric motors


The FDM monitoring system (Fourier Diagnostics Monitor) is designed to monitor the technical condition of AC motors according to the spectrum of the current consumed.

Distinctive features of the FDM system

  • The FDM system is implemented in a compact insulated enclosure, to which no wires are connected.
  • The FDM device does not require external power supply. The device is mounted directly on one of the three phase conductors, by which the motor is connected to the mains. The device is powered by the current in the conductor, which controls the motor current.
  • The FDM device will be automatically turned on when the electric motor is switched on.
  • The FDM device includes two processors to record and calculate the spectrum of current signal. It also has internal expert algorithm to diagnose the defect inside the motor.
  • The transmission of diagnosis result information from the FDM system to the SCADA system is carried out via Bluetooth wireless interface. The receiver can be a smartphone, a tablet, a ViAna-2 vibration analyzer or a stationary WDM signal receiver connected to the SCADA system.
