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.
Continuous Monitoring and display of Harmonic Voltage Levels. In the event of harmonic levels exceeding programmable limits, all capacitors will be switched off through overcurrent alarm

Counts, Stores and Displays the number of switching operations for each Individual Capacitor Stage and alarm is triggered, if the switching counter exceeds the programmable limits.

RMS current monitoring function provides excellent protection for capacitor banks without harmonic filters, 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 the required
reactive current.

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 to avoid overcompensation under light load condition.


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.

Preset up to three fixed capacitor stages, excluded from normal automatic operation.

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,
Apparent, Active & Reactive Currents,
5th, 7th, 11th & 13th harmonic voltage content &
Total capacitive power required to meet target power factor setting.


Alarm Signals for:

Undercompensation,
High harmonic levels,
Overcurrent,
Switching Counters,
Fault in Voltage Circuit ( U=0 alarm ),
Fault in Current Circuit ( I=0 alarm ) &
Fault in Capacitor Stages (C=0 alarm).
Optional extension of the EMR 1100S to EMR 1100 full version by means of
software updating enables:

Potential Free Tariff Switching contact to select Dual Power Factor Setting, Remote indication of measuring values via RS 232 interface & historical data Communication with Building control systems.
