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.

Temperature Data Acquisition
THERMES-USB
Physitemp’s Thermes high accuracy data acquisition system has been redesigned to create a more versatile USB model. The new system requires no internal connections to your computer and simply connects via an external USB port on your laptop or desktop computer. Two versions of the data acquisition system are available. The standard version, THERMES USB, is connected to your computer USB port. The wireless version - THERMES USB WFI, can be either directly connected to a USB port or, with the included wireless receiver, positioned up to 100 feet from the host computer. Each unit will accommodate up to 7 type T thermocouple sensors and multiple Thermes units may be connected to the same computer for more thermocouple inputs. A high accuracy electronic cold junction compensation circuit maintains typical system accuracy of ±0.2°C over an ambient temperature range of 15 to 35°C. Individual offsets may be added to each input in software to facilitate individual calibration of each channel. (see THERMES-USB WFI)

Contact Resistance Meter
The Motwane Manufacturing Company
High contact resistance values are a definite cause of the failure or less than optimal performance in a wide variety of electrical devices. Contact resistance testing is therefore most critical to measure the resistance of electrical connections in switching devices, circuit breakers, isolators, busbars, relays, joints, connectors, cables, and cable joints. The device helps to find destructive or corroded contacts and hence protects substation devices from damage.
