Rated output (VA): Rated output varies according to different combinations of accuracy levels and rated current ratios
.
Insulation level:
Primary winding to secondary winding and ground frequency withstand voltage: 42 kV/1 min.
Withstand voltage between phases of secondary winding and to ground at working frequency: 3 kV/1 min.
Lightning full-wave impulse withstand voltage: 75 kV
The withstand voltage of lightning full-wave impact is 75 kV.
Installation, use and maintenance:
Transformer to the use of units need to check the packing box should be accompanied by a packing list, product certification, instruction manuals and factory certificate of conformity.
Before using the transformer, the grounding bolt should be properly grounded.
During operation, the secondary winding must be reliably connected to the load, and the unused secondary winding must be shorted to the secondary outlet terminal to ensure safety.
The secondary winding must be connected to the load reliably during operation.
