Three Phase Servo Voltage Stabilizer


Sen & Pandit also offers Servo Voltage Stabilisers for 3 - phase systems. These usually have three single-phase servo stabilisers connected in STAR configuration for 3-phase application with individual sensing for each phase and to provide constant output in each phase even with unbalanced supply or unbalanced load.

Features

A versatile control panel at the top provides:
  • A voltmeter with a selector switch which can monitor any line voltage
  • Three ammeters to monitor output current continuously at each phase.
  • A miniature load ON-OFF switch actuates an AC line contactor which in turn actuates the 3-phase load system.
  • A reset switch counteracts tripping of supply to load. This switch will not reset the system unless source of tripping is removed

Automatic tripping of the load system in case of:
  • Single Phasing
  • Under or over range of input supply voltage in any phase.
  • Over loading in any phase.
  • Three voltmeters ( in each single phase unit) to monitor each phase to neutral voltage (both input and output) continuously.
  • Buzzer to indicate input over voltage or under voltage in any phase.
  • Manual setting facility.
