James A Booker, president of JA Booker Consulting and Dan Ninedorf, president of Ox Creek Energy Associates, will be presenting the corona technology course seminars beginning in January 2001 in the US.
Corona occurs typically at 5kV AC and above in many types of equipment including electric motors, switchgear, substations, transmission line insulators and conductors. The two-day long seminars will cover in detail what corona is; when, where and why it occurs; and what the true costs and prevention methods are.
