Transmission line simulator 

3 phase AC long transmission line having ACSR conductors 37 0.146 with spacing 6.7meters to transmit the power of 90 MW at 0.9 p.f.

The panel consists of the following

1. Auto Transformer    01 nos      Single phase., INPUT   230 V, 50 Hz, OUTPUT   230 V, 15 Amp
2. Single Phase Transformer    01 nos      1 KVA, 110V   220 V, 50 Hz. with equivalent Xe 0.04Henry at Sending End.
3. Single Phase Transformer    01 nos      1 KVA, 220V   220 V. with equivalent Xe   0.44 Henry at Receiving End., Both transformers are of good regulation quality.
4. Single Phase Inductive Load   220V, 5A arranged R & L with C in parallel 01 Nos    to operated at 0.9 lag P.F.
5. Transmission Line   Arranged in 3 phases separately to represent a line, 80 km to 400 km long with R, L and C divided in 5 sections with short circuiting switch or solid plug key for each section, Complete system with auto transformers, ON   OFF contactors, voltmeters, ammeters & wattmeter along with load to be arranged on panel to study the performance of T.L. for one phase under various conditions. The sending end voltage on the simulator is 220 V 50 Hz single phase so that if full load transmission is 100 MVA, that of the equivalent miniature system will be 0.872 KVA.
6. Variable Speed Drive    01 nos      To be used as ON   OFF restricting phenomena when T.L is to be investigated for ‘OVER VOLTAGES DUE TO RESTRIKING’.
7. Graded Over Current Protection   By using STATIC   INDUCTION TYPE OVER CURRENT RELAY mounted on panel with terminals of T.L. brought out for connections and arranging graded over current protection with three static relays in three sections.
