Neutral Ground Resistors protect industrial power systems.
2015-01-29 14:30:48| Industrial Newsroom - All News for Today
Comprising GRE1 grid resistors in weatherproof, IP23-rated enclosures with high voltage insulation, Milwaukee Resistors NGR series combines line-neutral (1.39–8 kV) and system (2.4–13.8 kV) voltages with performance to +760°C. Drop-in replacement solutions provide ground fault, overvoltage, and short circuit protection for generators and transformers in wye (star) configurations. Current ratings range from 100–1,000 A, and resistance ranges from 1.39–80 Ω with tolerance of ±10%.

High Power Shunt Resistors Ultra-Low-Ohmic.
2014-04-24 14:30:42| Industrial Newsroom - All News for Today
High-power, ultra-low-ohmic shunt resistors of PSR series include 4 W PSR400 and 5 W PSR500. Due to precision welding, products support high power requirements and ensure measurement accuracy even in ultra-low-ohmic (0.2 mΩ) region. Use of high-performance alloy for resistive metal optimizes temperature coefficient of resistance. Typical uses include current detection (detecting overcurrent conditions or remaining battery level) in automotive systems and industrial equipment applications.
