Reliable and steady heavy duty high voltage test fixture. made with stainless steel and aluminum.
Electrical insulation for up to 30 kV
High temperature up to 250 C (Teflon) or 300 C (ceramic), can be set in an oil bath for high temperature test, or inside a temperature oven.
Bottom electrode is stainless steel.
Top electrode is a M3 ball (replaceable) and spring loaded to maintain the pressure and good electrical contact during test.
Can be used for poling of piezoelectric ceramic and polymers, high voltage ferroelectric polarization loop test, high voltage dielectric breakdown test, or capacitance measurement inside an oven.
This fixture has two 1 m long coaxial cable connected to the top and bottom electrodes. The other end is BNC male connectors which can be connected to LCR meters for capacitance measurement. The coaxial cable is high temperature insulation for 150 C operation.
It also has a K-type thermcouple (male) for monitoring local temperature (if your oven temperature is not uniform).()
