Voltage drop Sample Clauses
POPULAR SAMPLE Copied 1 times
Voltage drop. Conduct voltage drop analysis for determining electrical service feeders, branch circuit conductors, and conduit sizes.
Voltage drop. 7.1.5.1 Contractor shall be responsible for calculating system voltage drop levels. The maximum system transient impedance or minimum available transient short-circuit capacity, shall be used in making voltage drop calculations relating to motor starting, restarting and/or re-acceleration requirements.
7.1.5.2 The voltage drops which apply to the normal operation of the electrical systems shall be limited to a maximum of the values specified below, unless specific or special apparatus requires improved voltage regulation. The effect on secondary circuit voltages from transformer taps shall be disregarded for normal voltage drop calculations. The voltage drops shall be calculated on the basis of motor and apparatus rating and shall be distributed generally in accordance with the following:
Voltage drop. The voltage difference between the sending and receiving ends must not exceed 5% of the nominal capacity. In Scheme No. 1, at the end of this Annex, the general configuration of the project is described.
Voltage drop. After the electrification of villages under these projects, pumps for raising water from ▇▇▇▇▇ and for supplying water to the houses were installed in the villages. However, in the field survey we found that both pumps had broken down and were inoperative. These pumps had already broken down and been repaired before. The apparent cause of the breakdowns in each case was motor burnout due to reduced voltage. The electricity supply situation there was that the water raising and supply pumps were situated 400m away from the distribution transformer, and most of the villagers' houses were connected to the low-voltage distribution line in that interval. In the records of the Udon Thani substation referred to earlier, the demand peak occurs at dinner time, between 6pm and 8pm. In this period, when demand is concentrated, the decline in voltage is greatest at the ends of distribution feeders. The motors also run automatically at such times, and this leads to the pump motors burning out, due to the principle explained below. Incidentally, there is a law prohibiting the use of agricultural pumps at night, so they are not used in the same peak period. The reason voltage drop causes motor burnout is that, due to the properties of motors, a 10%
