PD Sensors - Partial discharge

External Flange Sensor EFS1 . The external flange sensor EFS1 is a wide-band UHF antenna for PD detection on GIS and GIL. Since it is wrapped round the unshielded flange connection, the flange dimensions are required on order. With the N-connector it can be directly jointed with a UHF preamplifier like the UHF1 and UHF2 or the preacquisition unit FCU2. Power Diagnostix offers two different models, for permanent and for temporary installation.Get price

"C-4" would not explode without use of detonation devices, even when dropped, beaten, shot or burned. It was not destabilized by water, an important consideration given the Vietnam climate. Because it could be safely burned, "C-4" was popular with GIs, who would break off a small piece of it for heating water or C-rations.Get price

Resolution - Introduction to GIS

Radiometric resolution is how finely a satellite or sensor divides up the radiance it receives in each band. The greater the radiometric resolution the greater the range of intensities of radiation the sensor is able to distinguish and record. Radiometric resolution is typically expressed as the number of bits for each band.Get price

Sensor - GIS Wiki | The GIS Encyclopedia

UseClassification of Measurement ErrorsBiological SensorsExternal LinksSensors are used in everyday objects such as touch-sensitive elevator buttons and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware. Applications include cars, machines, aerospace, medicine, manufacturing and robotics. sensorsensitivity indicates how much the sensoroutput changes when the measured quantity changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, the sensitivity is 1 cm/°C. Sensors that measure very small changes must have very high sensitivities. Sensors also have an impact on what they measure; for instance, a room temperature thermometer inserted into a hot cup of liquid cools the liquid while the liquid heats the thermometer. Sensors need to be designed to have a small effect on what is measured, making the sensor smaller often improves this and may introduce other advantages. Technological progress allows more and more sen...Get price
