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
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
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
Continuous scrolling display for set Current and set Time.
Wide input range 300mA to 12A and the trip time programmable from 300ms to 30 seconds.

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.)
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)
