Using Thyristors in Heating Applications
... In burst fire mode the thyristors are used in the form of a 'solid state contactor'. The thyristors are cycled on for a period, and then off. By varying the length of the on period relative to the off period the power to the load may be controlled. Thyristors have two advantages over contactors; the ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
