Power ( Load ) sharing between two Alternators in Parallel Operation condition Transfer of Power from one Alternator to other Alternator in Parallel operation Power sharing between one Alternator & Infinite Bus (3Ø mains) in Parallel Operation condition.

CONTROLSBasicPowerFactor: The value at which that power factor is to beset is selected by means of this control, which has a calibrated dialfrom0.81agto 1.00.DeadBand:Dependinguponthe KVARcapacityofeach capacitortobe switched the, relay response sensitivityhas to be adjusted. Thedead band control serves to adjust this, so that hunting isavoidedDeadBandControl: .

Meter range: 0.61agto 0.6Iead.   Digital automatic control relay for  intelligent  control of capacitor bank.Simple Commissioning: By automatic  identificaton of  threshold current(c/k  value),  phase angle, connected  capacitor  stages  and  switching sequences.Operator Overview: Through clear display  of  key  momentary values and operating  parameter.a. Power factor (cos Ø)b. Apparent (RMS), active and reactive currentsc. 5th, 7th ,11th ,13th harmonic voltage contentd. Total Capacitive power required to meet target power factor settingMonitoring of Harmonic Levels: By continuous monitoring and display of harmonic voltage levels. In the event of harmonic levels exceeding programmable limits, all capacitors will be switched off through over-current  alarm.Additional Protection for Capacitors: The RMS current monitoring function provides excellent protection for capacitor bank without harmonic filters, especially when resonancecause an increase in harmonic levels. Potential-free alarm contact.     Programmable overcurrent alarm threshold limit(from 1.05 to 3.0 x Irms).     Continuous monitoring for defective capacitor stages through self adjustment of control program.     Zero voltage and zero current tripping with alarm signal.     Kinked" control curve characteristics avoid overcompensation under light load.     Four-quadrant power control with LED display when active power is generated into mains.     Manual/automatic operation with ability to switch each individual capacitor      stage ON or OFF.     Target power factor setting adjustable from 0.80 inductive to 0.95 capacitive  in steps of 0.01.     Preset up to three fixed capacitor stages which will be excluded from normal  automatic operation.     Independent setting of capacitor swithcing time to match discharge time of capacitor stages.     Suitable for current transformers with rated secondary current of 1A-5A.

MRP11 is micro controller based single phase, reverse power relay with one measuring element. Relay operates for pure active reverse power only and will not cause spurious tripping due to PF fluctuations in the system. Relay can work as a reverse reactive power relay with an addition potential transformer.
