Hi,
I am going through the calculations and got few doubts. Could you please clarify them.
1. The drop shunt value when the TC length of 1 km is around 2.9 Ohm.
I read that the typical drop shunt value is around 0.5 to 1 ohm where as the value here is a bit different. Is that because of the Track circuit length?
Please clarify.
2.The relay current when no train present as per the calculations is 332 mA.
Yes, this current is fair enough for the relay to pick up.
The calculation seems correct but how to find the exact value as you mentioned that it is not correct.
Please help.
Thanks in advance.
Regards,
JJ.
