High Voltage Systems

1 lessons

Marine High Voltage (3.3 kV, 6.6 kV, 11 kV): safety rationale, vacuum and SF6 circuit breakers, neutral earthing resistors (NER), Castell key interlocking, PTW and earthing trucks.

This chapter collects 1 illustrated lessons on High Voltage Systems as part of Marine Electrical Systems, ordered as they are best studied. It opens with Marine High Voltage (HV) Installations — 3.3 kV, 6.6 kV & 11 kV Switchgear and Safety. Each lesson is written for MEO oral and written preparation: definitions first, then how the system behaves, then the checks and figures used in practice.
