A field coil for an electromagnetic rotor comprising multiple windings, each substantially entirely coated with a powder resin having a dielectric strength of at least in the range of 1000-1500 vmil. A particle monitoring system includes a particle detector, an air sampling device, and a computer. The at least one gas shift reactor is further configured to produce a high pressure steam stream. The control system compares a reference signal representing the desired force with the actual force from the load cell, to produce an error signal which controls the penetration force, thereby tending to maintain a desired penetration depth.
