PLN (PERSERO) UP2D TANGERANG}, year={2020}, url={http://156.67.221.169/2290/}, abstract={PMT Simultaneity Test. PMT is a protection component that functions to secure the electric power network and affect the reliability of the electrical system, the purpose of PMT's simultaneous calculation is to find out the individual PMT's working time in opening and closing conditions according to the type of PMT used, namely the Three pole type. This aims to determine the Simultaneity of PMT when the conditions of one phase disturbance to the ground so that the PMT can protect one phase or three phases so the PMT must protect the disturbance simultaneously. Based on the calculation results obtained by the PMT simultaneous calculation after maintenance in September, October, November, and December is the time difference between PMT when opening and closing in September ?t Close 4.25 ms and Opent Open 3.77 ms , in October ?t Close 5.6 ms and Open Open 71.4 ms , in November Close 53.7 ms and Open Open 3.6 ms , and in December Close 2.86 ms and Open 5.35 ms.} }
