Type: ADR133AADR233A(ADITYA Series)All settings are arranged in menus for easy understanding of parameter.Maximum settings in one displayThe relay shows all the parameters such current before ICT current after ICT, Primary current, Bias anddifference current.Similarly relay latches fault current, type of fault with date and time stamp. If relay is upgrade tocommunication then it can provide full disturbance record in COMTRADE format for detailanalysis.4. Current Transformer RequirementFor high speed operation under all fault conditions the minimum current transformer knee point voltageshould equal or exceed Vt≥4 * IF (A +C)WhereIFAC= Either the maximum three phase through fault current (as limited by the Tx impedance) or thehighset setting, whichever is greater.= The secondary winding resistance of each star connected CT= The CT Secondary loop lead resistance for internal earth faults.Note: Due to our policy to upgrade our products constantly, we reserve the right to supply products which may varyslightly from that indicated above.<strong>ASHIDA</strong> ELECTRONICS PVT LTD.Plot No. A-308, Road No. 21,Wagle Industrial Estate,Thane (W)-400 604.
