Line light
| Глоссарий в железнодорожной технике |
An indicator on the driver’s desk of an electric train that current is being drawn from the overhead wires. when the line light is lost (and cannot be reset) it is an indication that there may be a fault with the pantograph or overhead wires; this requires immediate attention to avoid serious damage.

- (1) notice given by a dealer (through autex) or customer of an interest in buying or selling stock, sometimes including specific volume and price; (2) approximation of where a specialist sees buy and sell interest to tighten the range to an opening price.
- Выражение интереса (бирж.)
- In nondestructive inspection, a response or evidence of a response, that requires interpretation to determine its significance.
- Nondestructive test response that requires interpretation to determine its relevance. these include such things as meter deflections, shadows on radiographs, blips on screens, or localized discolorations on surfaces. see also defect; discontinuity; indication, false; indication, nonrelevant. indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the significance of an indication. indication, false: test indication that could be interpreted as originating from a discontinuity where no discontinuity exists. compare defect; ghost; indication, nonrelevant. false indications are an economic liability for inspection because they must be investigated. indication, nonrelevant: indication due to misapplied or improper testing. may also be an indication caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance). indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation, or location.
- Nondestructive test response that requires interpretation to determine its relevance.4 see also defect; discontinuity; false indication; nonrelevant indication. indication, nonrelevant: indication that has no relation to a discontinuity that might constitute a defect.1 test response caused by geometry or by a physical condition that is not a discontinuity. indication, relevant: indication from a discontinuity (as opposed to a false indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size or location.1

- Nondestructive test equipment response to a discontinuity that requires interpretation to determine its relevance.4 in magnetic particle testing, a visible accumulation of magnetic particles that serves as evidence of a magnetic leakage field.
- Defect, discontinuity, false indication and nonrelevant indication. induced current magnetization: noncontact means for testing delicate ring shaped objects for circumferential discontinuities. the technique is based on the fact that a time varying current passing through an internal conductor, often a soft iron or laminated core, self-induces an encircling magnetic field. this time varying magnetic field will induce a secondary current circling through the ring. this secondary current then self-induces the toroidal magnetic field used for testing.
- Nondestructive test equipment response to a reflector, requiring interpretation to determine its relevance. compare crack; defect; discontinuity; indication, false.10 indication, discontinuity: visible evidence of a material discontinuity. subsequent interpretation is required to determine the indication’s significance.10 indication, false: test indication that originates where no discontinuity exists in the test object. compare defect; indication, nonrelevant.10 indication, nonrelevant: indication possibly caused by an actual discontinuity that does not affect the usability of the test object (a change of section, for instance) or that is smaller than a relevant indication. compare indication, false and indication, relevant.10 indication, relevant: indication from a discontinuity (as opposed to a nonrelevant indication) requiring evaluation by a qualified inspector, typically with reference to an acceptance standard, by virtue of the discontinuity’s size, shape, orientation or location. compare indication, nonrelevant.10,19
Pantograph, английский
- An apparatus fixed to the roof of electric traction vehicles to draw current from the overhead supply.
- A scissors-like mechanism used for raising and lowering studio lights. other devices can also perform the same function, sometimes better.
- A drafting instrument for copying drawings, plans, etc., either on the same scale or on an enlarged or a reduced scale. pantry 1. a serving room between kitchen and dining space. 2. a room for storage of food supplies; a larder. 3. a room for preparing refreshments, not complete meals.
- Пантограф
- An instrument to copy or reduce drawings.
- Folding traction current collection device mounted on the roof of a vehicle on a railway employing an overhead supply system. nowadays, pantographs are sophisticated aero-dynamically designed devices which can operate at high speeds without loss of contact and with built-in safety devices which reduce the risk of damage to wires in the event of a fault. a common problem is when a pantograph catches above the wire and pulls it down for considerable distances before it is noticed by the crew and the train stopped. modern pantographs are fitted with automatic detection and lowering devices. the horns (curved edges) of the pantograph are equipped with frangible pneumatic sensors which, if broken by a wire support, cause the detector system to lower the pantograph.
- On train equipment for collecting electricity from overhead power cables.
