Frequently asked questions
Go to help centerPartial discharge is an early indicator of insulation deterioration inside electrical equipment. By detecting it early using our ZWPD92 tester (via TEV or Ultrasonic sensors), you can schedule maintenance before a catastrophic failure or explosion occurs.
A simple voltage check cannot determine a battery’s true health. Our battery discharge tester applies a real dummy load (constant current/power) to accurately measure the actual remaining capacity (Ah) of the entire battery string and individual cells under stress.
Yes! All our diagnostic tools come with internal storage and are equipped with interface options like SD cards or USB. They include free PC management software that automatically analyzes the data and generates professional Word or Excel reports.
It perfectly identifies electrical anomalies like voltage sags, swells, transients, and harmonic distortion. Detecting these hidden issues early is crucial to prevent unexplained equipment resets, overheating of transformers, and premature motor failures in your plant.
