rotary spark gap

This can cause re-ignition of a rotary spark gap at low speeds.

First versions had rotary spark gap modulator.

Reginald Fessenden’s synchronous rotary spark gap and heterodyning principle allowed voice transmissions to become a reality.

This Magnifier was powered by an 11kV distribution transformer and used a variable speed rotary spark gap.

KGH used synchronous rotary spark gap transmitters.

This greatly reduces the likelihood of power arcing or "trailing arcs" in the rotary spark gap due to a high DC current.

A Rotary spark gap consists of a synchronous motor, stationary and rotating electrodes, and a phase shifting device as shown in figure 2. at the right.

At firing rates above 200 BPS the beating disappears quickly, and therefore Asynchronous rotary spark gaps are usually run at high speed.

The primary was connected to a bank of oil capacitors to make a tuned circuit, excited by a rotary spark gap at 20 - 40 kilovolts from a powerful utility transformer.

This transmitter was one of the first Marconi installations to use a rotary spark gap, which gave Titanic a distinctive musical tone that could be readily distinguished from other signals.

The output of a rotary spark gap transmitter was turned on and off by the operator using a special kind of telegraph key that switched power going to the high voltage power supply.

Rotary spark gap - These use a spark gap consisting of electrodes around the periphery of a wheel rotated by a motor, which create sparks when they pass by a stationary electrode.

The rotary spark gap fires by the same breakdown process as the static gap except for one major difference:-A rotary spark gap only has the option of firing when the electrodes are aligned.
