1. General Scope

 EMT CO., LTD. Pole Top Auto-RECLOSER  is installed for Automatic  tripping  as equipped  IDMT  curve  with   Polymer , Solid Insulated  RECLOSER of  installation on Distribution  Pole.

 AUTO RECLOSER shall be able to automatically trip on Overload Phase Fault Trip, and  Ground Fault , Sensitive  Earthing Fault, and RECLOSER  can automatically reclose  with  Reclosing controller as  programmed  sequence  to minimize  SAIDI, SAIFI.

2. Auto Recloser Function

 2.1  Automatic Fault Trip as Circuit Breaker with IDMT Curve

 2.2  Automatic  Reclosing as Programmed sequence 

 2.3  Available of SCADA system with RTU (or, Integrated RTU)

3. Automatic Trip  & Reclosing  Function

 3.1 RECLOSER  shall make Trip as IDMT Curve (IEC Class A curve ( Standard Inverse )

   * Very  Inverse (VI), Extremely  Inverse (EI), Other  T-C  Curve  is available  optionally.       

 3.2 RECLOSER  shall  close  automatically  as  programmed  reclosing sequence.       

 3.3 Automatic Reclosing Counts and Time Interval are programmable as User's application.      

 3.4  No reclosing function  shall make only one time trip
