Abstract


The phenomenon that often arises in a substation is the problem of partial discharge in
 outgoing cable insulation. Partial discharge is a jump of positive and negative ions that are
 not supposed to meet so that it can cause a spark jump. If a partial discharge is left too long
 it can cause insulation failure, the sound of snakes like hissing and the most can cause a
flashover on the outgoing cable. Then a partial discharge detection prototype was made in the
 cable insulation in order to anticipate the isolation interference in the outgoing cable. Can
 simplify the work of substation operators to check the reliability of insulation on the outgoing
 side of each cubicle. So it was compiled as a method for measuring sound waves caused by
 partial discharge in the process of measuring using a microphone sensor, the Arduino Mega
 2560 module as a microcontroller, the LCD TFT as a monitoring and the MicroSD card module
as its storage. The microphone sensor is a sensor that has a high sensitivity to sound, has 2
analog and digital readings, and is easily designed with a microcontroller. Basically the unit of
measure measured at partial discharge is Decibels. The results of the prototype can be
 applied to the cubicle and the way it works is to match the prototype to the outgoing cubicle
 cable then measure from the cable boots connector to the bottom of the outgoing cable with
 a distance of 1 meter. Then the measurement results will be monitored on the TFT LCD
 screen in the form of measurement results, graphs and categories on partial discharge. In
 this design the measurement data made by the microphone can be stored with microSD so
that it can make an evaluation of partial discharge handling in outgoing cable insulation.
