PALM, MALVERN — April 11, 2018 — Vishay Intertechnology, Inc. (NYSE: VSH) announced that it will exhibit at the 2018 IEEE PES T&D for use in Oil and Gas, Industrial, Railways and Renewable Energy Power System's Latest Grids and Winding Resistance. This exhibition is the largest and most comprehensive exhibition in the field of power transmission and distribution, April 16-19 at the Colorado Convention and Exhibition in Denver. The center will hold. Vishay will exhibit Vishay Milwaukee GRE1, GRE2 and GRE3 series high-power, high-current mesh resistors, RBEF/RBSF series winding resistors, and NGR series neutral grounding resistors at booth 2236.
Vishay's GRE1, GRE2 and GRE3 series grid resistors are suitable for locomotives, harmonic filters, precharging and discharging of capacitors in renewable energy and industrial systems, dynamic braking, load testing, heaters and neutral grounding applications. The device has a power rating of 36 kW at +40°C, operating temperature up to +415°C, resistance from 0.02Ω to 240Ω, tolerance of ±10%, inductance from 5μH to 150μH. The resistor uses double-sided insulation with maximum cooling efficiency , Can be installed in IP00, IP20 and IP23 enclosures, for indoor and outdoor use.
RBEF/RBSF series wound resistors are ideally suited for pulsed applications to meet the heavy load requirements of space-heavy systems. High resistance reliability, all-welded construction, with high temperature resistant silicone or glaze ceramic coating. Power ratings from 40W to 2kW, resistances from 0.010Ω to 525Ω, with simple hardware, respectively, can be mounted on brackets, or mounted in shielded or outdoor level sealed enclosures.
The NGR series devices feature a rugged, weather-resistant IP23 enclosure that can operate at temperatures up to +760°C. Resistors can provide ground fault, overvoltage and short circuit protection for Y (star) wired generators and transformers, without exceeding IEEE -32 temperature limit, line and neutral voltage up to 8kV, system voltage up to 13.8kV, current level up to 1000A. The device also has an on-site design to eliminate floating voltage in the assembly process.
