I'm new in this field but was told the triangle is a cable termination or starting point. Don't remember the defining word.
RE: CT symbols
The triangle represents the cable terminations.
The lower CT symbol shows a zero sequence CT, 100/5 ratio, encircling all three phase cables to measure ground fault current. The two lines on either side of the main power one line in the symbol represent the other two phases going through the one CT. The CT is probably a doughnut CT with a larger opening, mounted in the cable compartment of the switchgear so the cables can pass through on their way to the bus connection.
