| Summary: | Leakage current frequency components are
frequently used as a tool for surface condition monitoring
on polymeric insulation material and their pollution
severity. Fast Fourier Transform (FFT) is one of the
methods that are applied for the analysis, but it has some
limitation in non-stationary signal. This paper presents the
analysis of leakage current via online monitoring system for
high voltage application. Tracking and erosion test
complying with BS EN 60587-2007 is conducted on
polymeric insulation to monitor the set of different leakage
current patterns from capacitive, resistive and non-linear
activities. The information obtained from this online
monitoring allows the user to identify leakage current
performance in real time. The user can monitor the
performances at certain distances safely which it is the main purpose for online monitoring besides the accuracy of the measurement system, time and cost saving. |
