Product Q&A
Q:How much improvement in loss and noise does the full miter-joint multi-step round core offer vs. conventional flat-laminated core?
A:
Loss reduced by 5-8%; noise lowered by 3-6dB.
Q:Why must the HV tap switch be operated only after power-off? Any interlock to prevent live switching?
A:
Off-circuit type has no load-break capability. Mechanical interlock with tank cover.
Q:How is Y/D switching done in the terminal box? Does voltage change affect protection settings?
A:
Reconnect six bushings per wiring diagram. Yes, protection relays must be reset.
