Earth leakage circuit breaker
An Earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use residual current circuit breakers which instead detect leakage current directly.
A leakage occurs when fluid is lost through a leak.
In economics, a leakage is a diversion of funds from some iterative process. For example, in the Keynesian depiction of the circular flow of income and expenditure, leakages are the non-consumption uses of income, including saving, taxes, and imports. In this model, leakages are equal in quantity to injections of spending from outside the flow at the equilibrium aggregate output. The model is best viewed as a circular flow between national income, output, consumption, and factor payments. Savings, taxes, and imports are "leaked" out of the main flow, reducing the money available in the rest of the economy. Imported goods are one way this may happen, transferring money earned in the country to another one.
Duct leakage testing
A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow. The combination of pressure and fan flow measurements are used to determine the ductwork airtightness. The airtightness of ductwork is useful knowledge when trying to improve energy conservation.
Reverse leakage current
Reverse leakage current in a semiconductor device is the current from that semiconductor device when the device is reverse biased.
Sensory leakage is a term used to refer to information that transferred to a person by conventional means (other than Psi) during an experiment into Psi.
Valve leakage refers to flow through a valve which is set in the 'off' state.
Non-verbal leakage is a form of non-verbal behavior that occurs when a person verbalizes one thing, but their body language indicates another, common forms of which include facial movements and hand-to-face gestures. The term "non-verbal leakage" got its origin in literature in 1968, leading to many subsequent studies on the topic throughout the 1970s (including multiple studies by American psychologist Paul Ekman ), with related studies continuing today.
Carbon leakage occurs when there is an increase in carbon dioxide emissions in one country as a result of an emissions reduction by a second country with a strict climate policy.
