At present, the lightning arrester monitors have popularized in various large and small substations in China, and their own operating conditions will directly affect the safety of the power system. The lightning arrester's action and leakage current are usually monitored by the lightning arrester monitor. Due to poor sealing, the monitor may enter moisture or moisture during running, causing internal components to rust, or other causes of the monitor counter not functioning properly, and the leakage current indication is not allowed. Therefore, the "Procedures" stipulate that the lightninh arrester monitor should be inspected once a year. This instrument is our best choice.
Main features
The monitor count can be checked on-power/off-power
The accuracy of the monitor ammeter can be verified on-power/off-power
True RMS measurement, good stability
The inter-frequency output is strong in anti-interference ability under the online state
Standard sine wave output, the verification result is completely same
Built-in battery measurement, it's very convenient for on-site using
