Cylindrical Foil Resistor replaces wirewound RBR57 MIL devices.

2014-03-07 14:31:18| Industrial Newsroom - All News for Today

Designed as direct, performance-enhancing replacement for wirewound and metal film devices, non-inductive (<0.08 µH) and non-capacitive VTA57Z features TCR of ±0.05 ppm/°C nominal from 0 to +60°C and ±0.2 ppm/°C nominal from -55 to +125°C (+25°C ref) as well as load-life stability of <±0.005% after 2,000 hr of rated power at 70°C. Power ratings include 0.25 W at +70°C and 160 V max working voltage. Other values include 5 &Omega; to 100 k&Omega; resistance range and tight resistance tolerance to ±0.01%.

Reducing Arc Flash Risks with Electrical Maintenance Safety Devices

2014-03-06 22:34:00| Electrical Construction & Maintenance

This paper presents the case for discussion on the advantages and disadvantages of each method for generator grounding. Medium Voltage Generators are not designed to withstand full fault current during a single phase to ground fault. This is the main reason that medium voltage generators are connected to a system with either low or high impedances. There are many methods to ground generators. To find out what these methods are, please download this free whitepaper. read more
