Excelitas Technologies Corp.
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.

Electromechanica, Inc.
The rail inverter test system uses a pulse test methodology to verify proper operation of the IGBT switching elements in a subway car motor control. The system is designed to verify proper commutation of the switching elements. A large capacitor bank allows testing at DC voltages up to 1kV and peak currents of up to 3kA into reactive loads.The system also integrates self test capabilities and safe-to-turn-on (STTO) diagnostics to ensure no gross faults are present prior to the application of high voltages. Further the system includes dielectric withstand (hi-pot) test capability to ensure electrical safety.

ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.

LXinstruments GmbH
Manufacturers of electrical or electronic products are required by law to carry out an electrical safety test before placing them on the market. This final test takes place at the end of the manufacturing process and is therefore also referred to as an EOL test (end-of-line). Depending on the prescribed standard and directive, the following parameters are tested:- Leakage current and discharge current- Insulation resistance or the insulation strenth- Dielectric strength or electric strength- Correct installation of the protective conductor (ground continuity and ground bond test)- Faultless functioning of the product under the conditions defined for intended use (function or run test

ITS-9050 -
Innovative Technical Systems
The Innovative Technical Systems ITS-9050 Detector is a sensitive, harmonic mixing detector designed to measure millimeter-wave free-space radiation. It is ideal for measuring radiation patterns of antennas inboth the near and far-field. The ITS-9050 employs a free-running dielectric resonator oscillator (DRO) and an integrated harmonic mixer with a waveguide RF input that either connects directly to a circuit under test or to an antenna for radiation detection. The resulting IF is amplified and detected by an IF log-detector that drives a front panel LCD voltmeter to provide an indication of signal strength. A DC output voltage from the log detector is available on a BNC connector to drive external data acquisition instrumentation. Also, a sample of the IF output is provided for measurement on a spectrum analyzer.
