Description

Analysis of partial discharge signals.

Usage

1
analysis(x, threshold = 8e-3, n.levels = 4, ...)

Arguments

x

numeric, a partial discharge signal.

threshold

numeric, relative value. The threshold is calculated with the product of this value and the absolute maximum value of x. See no0

n.levels

numeric, number of wavelet levels

...

additional arguments for wavVarPD

Details

This function calculate the wavelet variance (wavVarPD), maximum location, range, length, energy, zero-cross ratio (nZeroCross) and the frequency and damping factor via the Prony's method (prony).

Value

A data.frame with:

RefMax

Maximum location.

W1, W2, ...

Wavelet variances of the first n.levels levels.

range

Range of the signal.

N

Number of samples of the signal.

energy

Energy of the signal calculated as the sum of the squared samples.

nZC

Zero-cross rate.

freq1, freq2, damp1, damp2

Frequencies and damping factors of the most energetic components of the Prony's analysis.
