Brand Name : Naren Electronics

Product Description

Owing to our skilled team of experts, we are engaged in proposing a wide gamut of AVR Panel. These panels are suitable for 60 MW with output arrangement of AC Voltmeter, PF meter, DC Voltmeter and DC Ammeter with Voltage control and Power Factor control. The offered range of AVR Panel is well-known among the users for the protection against voltage fluctuations. These panels are rigorously tested on well-defined parameters in order to remove all the possible flaws.

Features:

Fully Solid states control
Voltage Matching (While Synchronizing with Grid)
Sensing P.T Fuse Failure Protection
Local and remote control of volts and VAR/PF set Points.
Single Phase average sensing Circuit.
Auxiliary input monitoring.
Two independent Channels. Each channel will have One Auto mode (Close Loop Voltage Control) voltage regulator and one manual mode (close loop excitation current control) field current regulator and one optional 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 /GRID.
Follow Up to match auto and manual channel output.
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 with set points
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.
