I work for Siemens and we are contractors to Vector (POCO) in Auckland and work in the electrical distribution industry.
I cover almost all the aspects of electrical work. Electrician, line mechanic, faultman, fault location, HV , LV substations and repair work.
Also when involved in certain jobs I like to see what caused a particular fault and see if improvements can be made to prevent the same failure in future again.
The product of rotation, excitation and flux produces electricty.
