Vishay Intertechnology to Highlight Latest Grid and Ribwound Resistors at POWER-GEN International® 2017
MALVERN, Pa. — Nov. 21, 2017 — Vishay Intertechnology, Inc. (NYSE: VSH) today announced that the company will be exhibiting its latest grid and ribwound resistors for oil and gas, industrial, traction, and renewable energy power systems at POWER-GEN International® 2017, the world’s largest power generation event. Taking place Dec. 5-7 at the Las Vegas Convention Center, in Las Vegas, Nevada, Vishay will be highlighting the Vishay Milwaukee GRE1, GRE2, and GRE3 series of high power, high current grid resistors, RBEF / RBSF series of ribwound resistors, and NGR series of neutral ground resistors in booth 6736.
Vishay’s GRE1, GRE2, and GRE3 series grid resistors are optimized for capacitor pre-charge and discharge, dynamic braking, load testing, heater, and neutral grounding applications in locomotive, harmonic filters, and renewable energy and industrial systems. The devices offer high power ratings to 36 kW at +40 °C, high operating temperatures to +415 °C, a wide resistance range from 0.02 Ω to 240 Ω — with tolerance of ± 10 % — and low inductance from 5 µH to 150 µH. Featuring double insulation for maximum cooling efficiency, the resistors can be mounted in IP00, IP20, and IP23 enclosures for indoor and outdoor use.
Ideal for pulsing applications, RBEF / RBSF series ribwound resistors are designed to meet heavy-duty requirements in systems where space is at a premium. Providing high reliability, the devices offer an all-welded construction and are available with high temperature silicone or vitreous enamel coatings. The resistors feature power ratings from 40 W to 2 kW, a wide on-resistance range from 0.010 Ω to 525 Ω, and are available individually with simple hardware, open mounted on bracket, or mounted inside screened or outdoor-rated enclosures.
NGR series devices offer high temperature performance to +760 °C in rugged, weatherproof IP23-rated enclosures. Designed to provide ground fault, overvoltage, and short circuit protection for generators and transformers in wye (star) configurations without exceeding the temperature limitations outlined by IEEE-32, the resistors deliver extremely high line-neutral voltage to 8 kV, system voltage to 13.8 kV, and current ratings to 1,000 A. The devices offer a tied live design to eliminate floating voltages in the assembly.
