• The grounding system of the long wave transmitter is very large.
• In a polyphase AC system, an artificial neutral grounding system may be used.
• Students also learn about grounding systems, testing of grounding systems and personnel protective grounding.
• Students also learn about grounding systems, testing of grounding systems and personnel protective grounding.
• The total length of all wires of the grounding system is, covering an area of.
• A multipoint grounding system can solve several problems, but they must all be addressed in turn.
• Each transformer in an alternating current distribution grid segments the grounding system into a new separate circuit loop.
• The grounding system in all three of the series, didn't stop with the foiled backing on the pickguard.
• Grounding systems without low resistivity to the ground can still be effective in protecting a structure from lightning damage.
• A lightning rod and grounding system connected to the metal cupola roof provides a safe conduit for any lightning strikes.
• Hybrid computers can be used to obtain a very good but relatively noise in analog computing elements and grounding systems.
• Low-resistance grounding systems use a neutral grounding resistor ( NGR ) to limit the fault current to 25 A or greater.
• Conventional grounding systems did not work well in this location since the desert terrain had no water table and very little rainfall.
• During World War II, the U . S . Army required a grounding system for bomb storage vaults near Tucson and Flagstaff, Arizona.
• It's also part of the 60 Hz grounding system, and by virtue of its fiber-nature, part of the communications and control for the project.
• For transmitter stations working on frequencies below 30 MHz a good grounding is required for good function and sometimes excessive grounding systems are used.
• The station building for the transmitting plants and a house was established in the long valley above the Kochelsees, and extensive grounding systems were built.
• A very complex grounding system was needed to ensure the accuracy of the voltages leaving the potentiometer system, as any stray voltages could overwhelm the signal.
• The underlying reason for this is an unavoidable conflict between the two different functions of a grounding system : reducing electronic noise and preventing electric shock.
• Low resistance grounding systems will have a time rating ( say, 10 seconds ) that indicates how long the resistor can carry the fault current before overheating.
