Specialty Probes
Upgraded "bare" versions of our probes for space-saving installation into oil (or SF6) tanks are now available. These probes are similar to the VD series probes with somewhat lower accuracy at a somewhat lower cost. When installing these probes some information about the surrounding areas is required. The length of a VD-120 bare probe (120 kV) is 0.35 m. These units are threaded and can therefore be stacked into higher voltage units. The VD-60 and VD-120 are offered at 60 kV and 120 kV respectively. The bare probes are now available for use in air, but only at 60 and 1120 kV sizes.

High-Voltage DC Power Supplies
Higher-voltage and Higher-power Supplies require more complex design solutions. The heat to be dissipated and installation infrastructure, plus choice of insulation system in a HVPS are driven by the output voltage and output power which ultimately dictates packaging. Typical insulation systems are based on air, dielectric oil, epoxy, RTV Silicone and even Sulfur Hexafluoride (SF6). The method of cooling is a factor as well, the choices often coming down to air, water or oil, depending on the platform design requirements. These applications require Excelitas' detailed understanding to help choose the best design solution.

*High Current Switches
B-1002
Ross High Current Switches are available up to 36,000 amps continuous and over 1,700,000 amps 20µsec RC pulse, with voltage ratings of 6 volts to 400kV peak test. Standard Ross high current switches are built with 80 to 120psi air cylinder actuators. Air cylinder or motor operated for high contact force. Arcing contacts optional for closing current. G-10 epoxy glass laminate is standard insulation on most models. G-7 silicone glass is used on models available for RF applications above 100kHz. Most Ross high current switches are available with additional lengths of insulation, where the high voltage contacts need to be spaced at a greater distance from the actuator and control circuit. Voltage withstand value is at least doubled and the interrupt capability is much greater when high current switches are immersed in insulating oil, fluid or SF6 gas. For gas atmosphere, no modifications are necessary; however, oil or fluid immersion requires modification at a slight extra cost.
