摘要： PURPOSE: To simplify and accurately measure the dielectric loss of a power cable, by arranging a dummy cable which has the same constitution and the same detection element as a power cable to be measured and to which AC voltage is not applied in the same atmosphere as the power cable to be measured while measuring the dielectic loss of the power cable from the temp. difference of both cables.
CONSTITUTION: A power cable A to be measured and a dummy cable B are arranged in the same atmosphere. The power cable A to be measured has a conductor 1 and a metal sheath 1b between which AC voltage is, in turn, applied. Thermocouples 2, 3 are provided to the surfaces of the outermost layer 1c and the heating medium 8 covering the outer periphery of said layer 1c of each of both cables and the outputs of said thermocouples 2, 3 are measured by a temp. measuring instrument 6 such as a temp. recorder. As the substance covering the surface of the outermost layer of the power cable, a material of which the heat conductivity is low and is not changed by a temp., for example, air, a cork material or other org. materials are desired but there is no limit if a material has known heat conductivity. As the dummy cable, one having the same heat constant as the cable to be measured is used.

摘要： PURPOSE:To measure the temperature at a high accuracy by providing two optical fibers through a semiconductor thin film with a temperature change in absorbance characteristic to allow the passage of lights with two different wavelengths in the opposite direction. CONSTITUTION:Light with the luminous strength P1 of an LED11 with the center wavelength lambda1 is divided in two with a half mirror 21 and the light reflected at the right angle is detected with a light receiving element 31. Light transmitting straight is incident into an optical fiber 41, passes through a semiconductor 5 having a temperature characteristic in the absorbance and then, detected with a light receiving element 32 by way of an optical fiber 42 and a half mirror 22. Likewise, light with the luminous strength P2 of an LED12 with the center wavelength lambda2 is fed in the opposite direction. Outputs of the light receiving elements 31-34 are computed to calculate the temperature.

摘要： PURPOSE: To minimize the residual inductance of a Schering bridge circuit and improve the measuring accuracy, by using a shunt which has a large resistance value and is small in size as the shunt of the circuit and installing the shunt in the main body of the Schering bridge circuit together with an airtight case.
CONSTITUTION: A shunt 13 which has a large resistance value and is small in size is prepared by putting the shunt 13 in an airtight case 16 equipped with a refrigerant inlet 14 and refrigerant outlet 15 and forcedly cooling the shunt 13 with an inter refrigerant, such as insulating liquid of insulating oil, etc., or inert gas of nitrogen gas, freon gas, etc. Then the shunt 13 is installed into the main body of a Schering bridge 9 together with the airtight case 16. When the Schering bridge 9 is constituted in such a manner, its residual inductance can be minimized and the tan δ error can also be reduced. Therefore, the mesuring accuracy can be improved.

摘要： PURPOSE:To easily and cheaply provide a cooled cable, by pulling an airtight flexible hose into a duct and expanding the hose and laying the cable in the hose and filling a coolant in the hose. CONSTITUTION:The airtight flexible hose 2 of flexibility not lower than that of the cable is pulled into the duct 1. An elastic ball 4 is pushed into the hose 2 by the pressure of fluid 5 such as water, thereby expanding the hose. The cable is pulled into the expanded hose. Then, the coolant 7 is filled in the hose 2. Thus, even if the airtightness of the duct is low, the coolant can be filled. Therefore, the cooled cable can be manufactured easily and cheaply.
