NASA NTRS1971

Inexpensive system protects megawatt resistance-heating furnace against high-voltage surges

Coolant gas extinguishes arcing across the break in a heater element. Air-gap shunt which bypasses high voltage impressed across the circuit prevents damage if the resistance elements break and open the inductive circuit.

Stearns, E. J.↗

NASA NTRS1971

High voltage lightning grounding device

Grounding device insertion in wire termination cabinets and terminal block modification prevent lightning-induced high voltage transients from reaching inputs or outputs of solid state instruments and control systems. Installation minimizes wiring confusion and achieves 100 percent protection.
