Fig. 93: Setting down the voltage transformer
➭ Set the voltage transformer ① down on the voltage transformer frame. The cast-resin cone
of the voltage transformer must penetrate into the end adapter / cross adapter.
While doing so, pull the cable strap ⑮ slowly out of the end adapter / cross adapter, and
verify intact condition.
If parts of the cable strap are missing, remove the voltage transformer again and verify that
no residuals of the cable strap remain in the end adapter / cross adapter.
➭ The voltage transformer must be correctly seated on its bolted joints.
➭ Fasten the 3 voltage transformers with 4 bolt-and-washer assemblies ⑥ and washers ⑤
each (tightening torque: 20 Nm).
Connecting secondary
leads
Secondary leads are not pre-assembled on all voltage transformer types.
➭ Connect the secondary leads that have been supplied separately to the voltage transformer.
Observe the phase sequence!
