Understanding Earth Leakage Monitoring for 100V Lines
This information is about understanding Earth Leakage Monitoring for 100V Lines.
What is a 100V Line audio system?
A 100V Line audio system, also known as a "constant-voltage system," is a cost-effective and straightforward multi-speaker sound system to set up. These systems are commonly used in large areas where multiple speakers are needed across significant distances, such as in shopping centres, outdoor events, schools, and bars & restaurants.
There are many advantages to using a 100V line PA system, such as running numerous speakers from a single amplifier over large distances without losing audio quality.
What exactly is earth Leakage?
Earth leakage occurs when the current flowing in a system finds an alternative return path other than the active and neutral conductors. In audio systems, earth leakage can lead to mysterious hums and buzzes.
It is crucial to monitor earth leakage in the audio system using the monitoring circuit depicted below.
