Method and systems for determining dielectric breakdown voltages of fluid samples using dielectric fluid testers

A method for detecting a dielectric breakdown voltage of a fluid sample using a dielectric fluid tester, the method comprising:

• delivering the fluid sample into a container of the dielectric fluid tester, the container comprising an insulating cap, a housing, and an access port, the dielectric fluid tester comprising a first electrode, comprising a first test head, and a second electrode, comprising a second test head;
• applying a voltage between the first electrode and the second electrode;
• and
• determining the dielectric breakdown voltage by at least one of:
• adjusting a gap between the first test head and the second test head,
• adjusting the voltage between the first electrode and the second electrode,
• adjusting temperature of the fluid sample inside the container, or
• adjusting pressure inside the container.

A system for determining a dielectric breakdown voltage of a fluid sample, the system comprising:

• a dielectric fluid tester, comprising a container, a first electrode, comprising a first test head and protruding into the container, and a second electrode, comprising a second test head and protruding into the container, wherein the first test head and the second test head face each other and are separated by a gap;
• a power supply, electrically coupled to each of the first electrode and the second electrode and configured to control a voltage applied between the first electrode and the second electrode;
• and
• a pressure-controlling source, fluidically coupled to an interior of the container and configured to control pressure inside the container.
