Ashida Electronics Private Limited

 

^{ASHIDA Numerical 3 Phase Tx. Differential + Over Current Protection Relay}

 

The ADR211E is member of Ashida Numerical Relay family (Aditya Series) design to meet demandof low and medium switchgear control. The ADR211E is single pole EF relay with instantaneous highset and programmable output to simplify feeder protection wiring. The ADR211E continuouslymonitors earth current, through CT connections. The high-speed micro-controller samples thiscurrent through a 12-bit A/D converter. The micro-controller performs powerful Digital Algorithmsto find out Amplitude of current signal, and then this value is use for protection and meteringfunction. All measurement is tuned to fundamental frequency. Each input current is also displayedon 16 x 2 LCD display for metering.

Our range of relay is having following functions:
 

• Protection 
• Self-supervision
• Measurement

Following are the features of our range of numerical neutral displacement protection relay:

• Single Element EF IDMT with instant trip.
  
• Back - lit LCD display for settings.
  
• Display of fault current / Load current.
  
• Design using DSP technology.
  
• Latching of fault current up-to last 5 fault.
  
• Password protection for setting.
  
• Site selectable CT secondary (For Model AM00x02/x03)
• Relay can be made either IDMT or Define time.
• Programmable operating time in instantaneous element
• Suitable For REF Protection
