Inquiry Form

This PQA-3561 is 3P/3W and 3P/4W, power quality analyzer, using to test and evaluate power grid quality. It provides multiple analyzing for electric harmonic, voltage/current/frequency, 3-phase unbalance, power and energy, data recording and more.
The power quality analyzer helps to locate, predict, prevent and troubleshoot problems in power distribution systems. It is featured with big size memory, suitable for long-time analyzing and collecting data of power grid; its software analyzes data collected and uploaded into PC.

Applications of Power Quality Analyzer
1. Frontline troubleshooting - diagnose problems on-screen to get your operation back online immediately.
2. Diagnosis in advance - detects and prevents power quality issues before they occur.
3. Validate incoming power quality at the service entrance.
4. The power quality analyzer finds unreachable or intermittent issues.
5. Load studies - verify electrical system capacity before adding loads.
6. Evaluation - quantify energy consumption before and after improvements in order to save energy on electrical devices.
