X-Ray Tube Heating and Cooling - Sprawls

In order to evaluate the problem of x-ray tube heating, it is necessary to understand the relationship of three physical quantities: (1) heat, (2) temperature, and (3) heat capacity. Heat is a form of energy and can be expressed in any energy units. In x-ray equipment, heat is usually expressed in joules (watt-seconds) or heat units.

Insulators used in overhead power lines | electricaleasy

Hence, overhead power lines are always supported on insulators mounted on their support poles/towers. high mechanical strength in order to withstand the conductor load, wind load etc. high relative permittivity of insulating material so that the dielectric strength is high. Most commonly used material for overhead line insulators is porcelain.

Electrical Safety: The Fatal Current

Individuals have been electrocuted by appliances using ordinary house currents of 110 volts and by electrical apparatus in industry using as little as 42 volts direct current. The real measure of shock''s intensity lies in the amount of current (amperes) forced though the body, and not the voltage.

Breakdown Torque - an overview | ScienceDirect Topics

Breakdown torque: For an alternating current motor, this is the maximum torque that it will develop with rated voltage applied at rated frequency, without an abrupt drop in speed. Pull-out torque: For a synchronous motor, this is the maximum sustained torque that the motor will develop at synchronous speed for one minute with rated voltage applied at rated frequency and with normal excitation.
