As cbradley mentioned this is a Distribution Substation, a utility I assume. I doubt that there are any motors being fed in this substation and furthermore this substation is probably comprised of outbound feeder bays only.
Now look at it this way cbradley, I am not aware of what kind of scheme you have at your distribution substation, but consider the following scenario:
If you look at a basic two transformer substation feeding two separate buses and a normally open bus tie CB between them. You will typically not find a synch check relay involved in the closing circuit of this bus tie breaker, at least from my experience and the utility I use to work for. Now, if you think of one station service transformer (normal) being fed from one bus and the other station service transformer (emergency) being fed from the other bus why would the secondary’s of these transformers need a synch check relay if the HV primary bus tie breaker closing circuit does not?
My comments are only based on assumptions of the configuration of your distribution substation. There could be factors that I am not aware of that would could lead to unforeseen issues that would require a more thorough throw-over scheme.
