Power Control Relays

• Potential-free alarm contact.
• Programmable overcurrent alarm threshold limit (from1.05 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.
• Two control curves 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 with ability to switch each individual capacitor stage ON / OFF.
• Target power factor setting adjustable from 0.85 inductive to 1.00 capacitive in steps of 0.01.
• Independent setting of capacitor switching time to match discharge time of capacitor stages.
• Suitable for current transformers with rated secondary current of 1A or 5A.
