The magnetic material may be "air", but it is a transmission line transformer.

It is available in either low impedance or line transformer electrical configurations.

Many mass produced 100V and 70V line transformers are available at good prices from other distributors.

This cone acts like a tapered transmission line transformer.

Use of transmission line transformers in matching.

The sheriff fires a riot gun, which causes a nearby power line transformer to blow up, killing Nancy.

Includes 100V line transformer with taps.

CPA 6 with built in line transformer.

Fitted 100V line transformer and direct tapping, for 8 ohms selectable by rotary switch.

Occasionally, a low-pass section is included to compensate for excessive line transformer roll-off at the low frequency end.

Transmission line or "choke" baluns can be considered as simple forms of transmission line transformers.

In this configuration the total wattage load on the amplifier is derived from adding all the line transformer primary tap ratings together.

Pete Kenny was visiting to help move his grandmother to Illinois and said he heard the landslide as he watched power line transformers explode.

Like a geomagnetic storm, E3 can produce geomagnetically induced currents in long electrical conductors, damaging components such as power line transformers.

For example, some of these planned expenditures include $450 million for distribution lines, $55 million for line transformers and $110 million to improve substations.

Generally every AC power line transformer acts as an isolation transformer, and every step up or down has the potential to form an isolated circuit.

The balloon touched down positively and then became airborne again and contacted an electricity power line transformer post and the associated power cables, before finally landing.

The Guanella transmission line transformer (Guanella 1944) is often combined with a balun to act as an impedance matching transformer.

Internal hum neutralizing wiring coupled with magnetic shielding of the toroidal ribbon-to-microphone line transformer reduces response to stray magnetic fields by 30 to 40 dB.

These are sometimes made from configurations of transmission line and sometimes bifilar or coaxial cable and are similar to transmission line transformers in construction and operation.

DALLAS Imagine this: An Oncor power line transformer malfunctions, it surges electricity and most of your electronics, appliances and your air conditioner all get fried.

Several manufacturers build small (typically 115 mm (4.5")) diameter full-range drivers into miniature enclosures, and many of these include 25 or 70-volt line transformers, for use on commercial sound systems employing long speaker cables."

The line transformer was designed to have higher than normal leakage inductance to tolerate the short circuit occurring while the gap remained ionized, or for the few milliseconds until the high frequency current had died away.

This is opposite of most line transformers, which will produce full voltage to a load even if overloaded, unless the resistance of windings is too great to allow the excess current or until a winding burns out.

An inbuilt feature is a dual frequency switch selectable, high pass filter, used when feeding loudspeakers with poor low frequency response, inadequate line transformers or re-entrant horns, when it is desirable to limit low frequency signals.
