Elmeasure Earth Leakage Relay

Item Code: ElmeasureEarthLekageRelay

Intelliegent Earth Leakage Realy (iELR)

Elmeasure a trend setter has introduced this for the first time in industry incorporating high performance microcontroller based IELR with 4digit 7 segments RED bright Digital display, which is very unique as compared to other’s conventional ELRs. 

Microcontroller based Peak detection and value display. Provides faster and reliable protection to the expensive equipments. 

  • Protects control panels and switch boards from flame leakage
  • Protects motors / transformers / feeders / DG etc., against earth leakage
  • Hazardous and sensitive industries like oil refineries / pulp industries / electrical distribution can be protected
  • Complete protection for control engineering and mining industry

Salient Features :

  • True RMS measurement
  • Clearance and Creepage distance meets UL 508 Safety standard
  • Inverse curve - Trip time is inversely proportional to leakage current. This ELR is Intelligent, when the Leakage current is 10 times higher than the set current it trips 10 times faster.
  • Field programmable trip current and trip time through front panel keys with password protection

Elmeasure Power Factor Controller

Item Code: Elmeasure

Intelligent Power Factor Controller (iPFC)

It is an intelligent Power Factor Controller with 3 phase sensing and inbuilt intelligence to increase the capacitor life time by adapting capacitor switching information and ON time. 

Unlike conventional power factor controllers which sense voltage from two phases and current from the other phase, Elmeasures IPFC is based on 3 phase sensing which renders it accurate for controlling power factor even an unbalanced condition 

Available in 6,8 and 12 stages.
  • In all Incomers
  • Fixed power factor corrections individual (e.g. motor, transformers, lighting, etc.)
  • Group fixed power factor correction (several equipments connected in a group)
  • Capacitor banks of tuned and detuned
  • Harmonic trap applications (e.g. UPS, Frequency Drives and Converters, etc.)

Salient Features: 

  • Three Phase Sensing
  • Intelligent Power Factor Controlling based on the capacitor bank switching history (No of Operations, ON Time) - improves the capacitor life time
  • Automatic or Manual Control (manual control with power backup option)
  • User Programmable:
    • Star/Delta
    • Lead and Lag Limits
    • PT and CT Ratios
    • CT Secondary
    • Minimum Switching Time (1-99 seconds)
    • Minimum Discharge Time (1-99 seconds)
    • Minimum capacitor On time (1-99 seconds)
    • Minimum Sensing Current for Controlling Operation 100mA - 500mA
    • User programmable capacitor value
    • Programmable no of capacitors
