EXAMPLE OF PRACTICAL APPLICATION
Straight Line Protection (2spans)
Dos and Don'ts
Don't install transmitters for multi stacked protection with
multiple spans
Don't install transmitters with more than three spans in straight line protection.
Don't install transmitters in the same direction
for multi stacked protection.
Don't install transmitters in the same direction for
straight line protection.
●
