Abstract :
In carrying out the maintenance of the circuit breaker (CB) so that the CB can work optimally and not cause losses, a contact resistance test is carried out. The results of this contact resistance test must be in accordance with the manufacturer's standards that have been set because if the contact resistance value is large, it can cause large power losses. The results of this study obtained the value of the contact resistance at the CB Bay Conductor Liwa 1 in the R phase of 41.6 ??, in the S phase of 40.8 ??, and in the T phase of 36.9 ??. Then the power loss is calculated according to the results of the contact resistance value and the conductor load current, obtained in phase R of 6.007 × 10-5 kW, in phase S of 5.891 × 10-5 kW and in phase T of 5.328 × 10-5 kW. After that, the energy loss was calculated and obtained in the R phase of 0.044 kWh, in the S phase of 0.044 kWh, and in the T phase of 0.04 kWh. After that, the calculation of the cost of electricity that is not sold is obtained in phase R of Rp 65.68; in the S phase of Rp 63.6; in the T phase of Rp. 57.3. So it can be concluded that there is no big loss in this Liwa 1 conductor. But maintenance must still be done to keep from causing losses.
