Automated Hipot Test Station for Beverage Machine Manufacturer

Posted in Business Intelligence, Digital Workplace Solutions, Food and Beverage, LabVIEW, Manufacturing Automation and Intelligence, Test & Measurement Automation


DMC developed an automated Hipot (High Potential) test station for a beverage machine manufacturer. The system is used to verify proper electrical grounding and isolation in the chassis of the beverage dispensing machine.






DMC delivered an automated system for testing beverage machines as they exit the production line.  The High Potential (Hipot) tests are used to verify that the insulation of a product or component is sufficient to protect the operator from electrical shock.  This test is crucial from a safety perspective, requiring high reliability.  DMC developed a system that ensures each machine successfully passes the Hipot test before continuing to the next step in the testing process.  The test station is integrated into a central database that tracks the product through the entire testing process.  This provides complete traceability and eliminates the possibility for an untested or failed device making its way to a customer.  An intuitive user interface allows quick, consistent tests.  Since the process is highly automated and the user is guided through every step in the process, operator training is significantly minimized.
