Sensor Rack Phasing

What is Phase Balancing?

There are two ways in which a Sensor rack can be phase balanced, straight or balanced.
Phase balancing refers to way in which the circuits are landed in the rack. 
 

Straight Phasing  in an SR48

In the above example circuits 1 - 32 land on phase A.
Circuits 33- 64 land on phase B.
Circuits 65-96 land on phase C.
This is an example of straight phasing

Balanced Phasing in an SR48

In the above example notice that circuits are not in numerical order.
Phase A contains circuits 1,2,7,8...
Phase B contains circuits 3,4,9,10...
Phase C contains circuits 5,6,11,12...
This is an example of balanced phasing in which the load is distributed between the phases.
