PCS+ on multi source network

[TC]

Hi, I have dual-source switchboard (with ATS).

2 sets of such switchboard.

Each of this switchboard will have VSD hence needing AHF on each side. 

Normal condition, each will be fed separately. (inter-tie open)

Ideally, we will size this AHF to cater for "emergency" where single source will feed both switchboards, with inter-tie close.

Do we really need 3 CT measurement points per AHF?

Does it work with our PCS+ (each AHF will need multiple of 200A for e.g. to work in parallel)

If not, any recommendation?

Hello TC,

Good day!
Yes, you're right, we need 3 CT measurement points per AHF in this scenario.

We recommend you to use summation current transformer which can add multiple CT measurements.
