System and method for measuring the dielectric strength of a fluid

摘要

A system is disclosed for monitoring the quality of an internal fluid contained in an apparatus. The system includes a pulse input port, a test gap unit, and a reactive impedance unit. The pulse input port receives a test pulse input signal frm a pulse source. The test gap unit provides a test voltage across a test gap while the test gap unit is immersed in the internal fluid within the apparatus. The test gap means has an inherent capacitance. The reactive impedance unit provides an impedance in series with the inherent capacitance of the test gap unit that restricts transfer of current to the test gap, and is coupled to the pulse input port and coupled to the test gap unit.
