Chapter 6 Checking the

external circuitry

About this chapter

This chapter describes what to check and which checks that should be made to ensure a correct
connection to the external circuitry, such as auxiliary power supply, CT’s and VT’s. These
checks must be made with the protection terminal de-energised.
