With this Power Lines Tester the voltage between phases and the neutral, the working frequency, and the Ground-Neutral Loop Impedance are monitored for critical power lines. The voltage between phases and neutral is measured with the aim of detecting voltage discontinuities among phases. Measuring the working frequency is also an effective way of detecting voltage discontinuities and voltage anomalies. As a result, we may detect voltage decondensations between phases, voltage anomalies among phases, or even phase failure. Ground-Neutral Loop Impedance can be measured to detect ground faults, ground connection deterioration, and phase failure immediately.
