This study discusses the measurement of Partial Discharge (PD) in air insulation. Partial Discharge Measurement is very important to know the condition of electrical equipment. The cause of partial discharge is not only old equipment, but also from setup errors and insulation problems. In this research partial discharge measurement was performed by using electrical methods. Electrical method use RC Detector. The modeling of partial discharge was done by using needle-plane electrode distant 1 cm in air insulation. Partial discharge measurement parameters include the measurement of Background Noise (BGN), Partial Discharge Inception Voltage (PDIV) and PD Waveform. The Partial Discharge measurement result show that Vpp of BGN ON is higher than Vpp of BGN OFF. The negative PDIV signal first appeared for the RC Detector at a voltage 3.55 KV and Positive PDIV at 4.01 KV. Negative and positive PD waveform for RC Detector at 5 KV, 5.5 KV, 6 KV, 6.5 KV and 7 KV respectively, it has been found that the fall time is greater than the rise time, and peak to peak voltage (Vpp) will be greater when the applied voltage is greater.

Electricity basically has become the main requirement for human beings on earth. Thus electrical reliability is the most important things so that electricity flow to consumers is not interrupted. The most electricity vital is substation, there are some disturbances that commonly occur in high voltage equipment in substation such as disruption due to old tool, interference due to human error, and natural disruption resulting in equipment damage. To minimize these disturbances we need a tool that can detect interference, namely sensors. One of disturbances in substations is Partial discharge. To find out a partial discharge in voltage equipment there are several ways such as measuring using a RC sensor detector and using an antenna. This study discusses partial discharge sensor that will detect the level of partial discharge that exists in high voltage equipment such as transformers, cables, GIS (Gas insulated switchgear) and others. Spiral antenna is the main topic in this research by making spiral antenna with 10 segments. The steps in making this antenna are firstly carried out design and simulation using CST 2018 software then implementing antenna on FR4 epoxy PCB. The antenna is tested for its characteristics based on several parameters such as VSWR, RL, and Bandwidth. This test is carried out using a VNA measurement tool. The test results show that this 10 segment spiral antenna produces a VSWR value of less than 2, an RL value of less than -15, and bandwidth included in signal frequency by partial discharge is around 300MHz - 3GHz.
