RM 9806

BARON POWER LTD., Indian Distributor of FRAKO, Germany, markets the world renowned Micro Processor based Power Factor Relay.  BARON also manufacturers custom built system for Power Factor management and offers services that solve power quality issues.


SALIENT FEATURES
6 Step Micro Processor based control Relay for intelligent control of capacitor banks with 6 control contacts.
Patented control characteristics (Kinked) – no overcompensation during low load condition.
High class sensing Accuracy of 0.4%.
Overcurrent Trip Function – Protection for Capacitors.
Zero-Voltage and Zero-Current release.
Four Quadrant Measurement.
Automatic Adjustable Switching Delay.
Versatile indication and message in the Display
Compliance to Indian & International Standards

PURPOSE: Power Factor / Reactive Power Management in Electrical Installation.

DESCRIPTION
Simple Commissioning by automatic identification of threshold current (c/k value), phase angle, connected capacitor stages and switching sequences.
Extensive Analysis Record In automatic mode, displays :
Connection Faults.
Capacity Step Faults.
Recognized step sequence.
RMS current monitoring function provides excellent protection for capacitor banks, especially when resonance cause an increase in harmonic levels.
Enhanced Equipment Life through:
Cyclic switching of capacitor stages of same rating
Accurate switching of capacitor stages, preventing unnecessary switching for responsive control
Continuous optimization of switching delay according to required reactive current.
Potential-free alarm contact.
Programmable overcurrent alarm threshold limit (from 1.05 to 1.95 x Irms)
Continuous monitoring for defective capacitor stages through self adjustment of control program.
Zero Voltage and Zero Current tripping with alarm signal.
To control curve characteristics 
to avoid overcompensation under light load.
to avoid inductive reactive power under regeneration conditions.
Four Quadrant power control with LED display when active power is generated into mains.
Manual/automatic operation to switch ON & OFF each Individual capacitor stages.
Independent setting of capacitor switching time to match discharge time of capacitor stages.
Suitable for current transformers with rated secondary current of 1 Amps or
5 Amps.
Clear digital display of key momentary values and operating parameters :
Power Factor,
Total Voltage Distortion Factor (% THVD)
Number of active capacitor steps.
Alarm Signals for :
Overcurrent,
Fault in Voltage Circuit (U=0 alarm )
Fault in capacitor stages.
