| Summary: | This paper discusses the effect of metal box holes on Partial Discharge <br />
<br />
<br />
(PD) measurements and detection on electrical equipment that is characterized by <br />
<br />
<br />
metal enclosed. Methods used in the detection and measurement of PD is an <br />
<br />
<br />
Ultra-High Frequency (UHF) according to IEC60270. This method utilizes the <br />
<br />
<br />
energy of electromagnetic waves emitted by the PD source are derived from the <br />
<br />
<br />
metal box. Advantages of using this method is the ability to detect and measure <br />
<br />
<br />
without having to turn off the test object (HV equipment). <br />
<br />
<br />
The sensor used for this test is a loop antenna. This loop antenna is <br />
<br />
<br />
obtained from previous research where the antenna is designed as indentic as <br />
<br />
<br />
possible so that it can be used on PD measurement simultaneously. <br />
<br />
<br />
The PD test is performed with a variety of box holes and loopholes on <br />
<br />
<br />
metal box. It aims to determine the effect of the existing hole on the metal box. In <br />
<br />
<br />
addition, testing has been done with variety of voltage and variety of antenna <br />
<br />
<br />
laying distance. Measurement results are then compared. |
