If safety ground in Sec 7.1 Step 6, have operations re-install safety ground. Document on Signoff/Data Sheet. Connect neutral or center tap ground connections. Torque connections IAW Table 3: Torque Value Chart. Document torque on Signoff/Data Sheet and record re-connections on Verification Sheet. Install ground resistors. Torque connections IAW Table 3: Torque Value Chart. Document torque on Signoff/Data Sheet and record re-connections on Verification Sheet Install potential transformer fuses. Document and verify on Verification Sheet. Remove all test leads, temporary phase jumpers and temporary grounding jumpers installed in this procedure. Document and verify on Verification Sheet. Unterminated Transformer Setup The work group shall walk down both ends of any affected cable(s) to be sure they are connected or isolated at their source to prevent any arcing. arriers at both ends, with warning signs attached to alert all in the area before any testing starts. Perform continuity checks between all phases of the transformer on primary side and secondary side. Install temporary phase jumpers from phase to phase on both high side and low side. See Figure 2: Transformer Jumpers for typical transformer installation. Install temporary grounding jumpers to transformer frame, connecting to jumpers installed in Section 7.5 Step 2.
