    Abstract: Described herein are dielectric fluid testers for determining dielectric breakdown of fluid samples, systems comprising such testers, and methods using thereof. A dielectric fluid tester comprises a container and two electrodes. The test heads of these electrodes protrude inside the container and face each other, forming a gap. In some examples, one or both electrodes are movable for adjusting the gap and/or the volume inside the container available for a fluid sample. For example, the container includes two internal seals, one of which has a fixed position and is slidably coupled to a respective electrode. The other seal is slidably coupled to the container and moves together with the corresponding electrode. The container comprises an access port, providing a fluid communication between the fluid sample and an external pressure-controlling source. In some examples, the access port is used to deliver and remove the fluid sample from the container.

    Abstract: The present disclosure provides an apparatus and method of use thereof for compressive creep testing of materials in the presence of fluids. The apparatus includes a cantilever arm connected on a first end to a cantilever pivot and including a weight holder on a second end; a first platen connected to the cantilever arm via a swivel located between the first end and the second end; a reservoir; and a second platen disposed within the reservoir and positioned to secure a sample between the first platen and the second platen when a force is applied via the weight holder and the first platen to a sample. Electrical properties of the material can be monitored and measured during the compression creep testing.
