7.20.8 Laying wires of secondary equipment
NOTICE
Falling below the minimum distances of secondary wires
Too small minimum distances between the secondary wires of the instrument transformers
and primary live parts can cause an internal arc during operation.
⇨ Observe the minimum distance ≥ 190 mm for laying the secondary wires, and verify it.
1. The secondary wires of the instrument transformers are combined in a flexible steel tube
and led into the metering panel.
2. Fasten the flexible steel tube at the lateral plastic plate using cable straps. Holes for the cable
straps are prepared in the plastic plate.
