Calculation and insertion of new ancillary data checksum is controlled by the ANC Checksum Force bit in the configuration and control registers. If a checksum error is detected (calculated and received checksums do not match) and the ANC Checksum Force bit is set, a new checksum will be ...
Alternatively, an energy efficiency method introduced by the Code could also be used for preliminary cable sizing. This energy efficiency method for cable sizing requires the calculation of themaximum allowable conductor resistancebased on the maximum copper loss requirement as stipulated in the code. ...
The calculation of safety factor of overhead cable hanging or suspension is ordinary strength should not be less than 3; the calculation of safety factor of auxiliary suspension strength should not be heart in 2. overhead cable line each should set up a cable wire. There are two layers of ...
