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.

Applications:
  • 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
Intelligent Earth Leakage Relay




 
  • 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.Inverse curve
  • Field programmable trip current and trip time through front panel keys with password protection
  • Continuous leakage current display (Programmable) –Leakage current display to enable the user understand the quality of Electrical network / Machine online. This can be disabled through setup.
  • Continuous Display of Trip Leakage current (Programmable) Leakage current continously displayed to enhance the user to understand the quality of Electrical network / Machine online.This can be displayed through setup if required
