AVR Control Panel

We are engaged in offering a premium quality array of AVR Control Panel. These panels are appropriate for 60 MW alternator with output instrumentation of AC Voltmeter, PF meter, DC Voltmeter and DC Ammeter with Voltage control and Power Factor control and protect against voltage variations. Our offered range of AVR Control Panel is available in standard sizes and can also be customized as per the need of the clients. 

Technical Features:

• Fully Solid states no moving Parts.
• Solid State Build Up.
• Voltage Matching (While Synchronizing with Grid).
• Sensing P.T Fuse Failure Protection.
• Local and remote control of volts, VAR and PF set Points.
• Single Phase average sensing Circuit.
• Auxiliary input monitoring.

     Two independent Channels. Each channel will have One Auto Channel (Close Loop Voltage Control) and one manual channel (close loop  excitation current control) and one dedicated manual (having one servo controlled auto transformer, One Current limiting Choke and bridge rectifier).

• Q.D.C for  parallel operation with other DG/TG sets /Or GRID.
• Follow Up to match auto and manual channel output. Under/ Over excited MVAR Limiter.
• Protection against over fluxing (frequency Roll off)
• Over Voltage Protection & Under/Over Excitation Protection.
• Stator current limiter.
• Auto Power Factor controller & VAR Controller.
• Meters to Measure input Voltage, Power factor, Filed Voltage filed current and Null Voltmeter.
• Micro Processor Annunciator with audio and visual alarm for different fault.
