Disruptive discharges due to air inclusions
Will damage the cast-resin bushing.
➭ While installing the voltage transformer, let excess air out of the plug-in connection with
a cable strap.
➭ Verify intact condition of the cable strap. If the cable strap was damaged when it was
pulled out, remove the voltage transformer and eliminate the residues of the cable strap.
➭ To let excess air out of the plug connection while mounting the voltage transformer,
fit a nylon thread or a cable strap into the inside cone of the panel connection cover.
➭ Insert the primary terminal of the voltage transformer slowly into the inside cone of the
panel connection cover, pulling the cable strap out at the same time.
➭ Fit plain washers on the threaded rods of the fixing bracket stecken. Bolt the voltage
transformer uniformly together with the panel connection cover using the M10 nuts.
Tightening torque: 30 Nm.
