HIGH VOLTAGE INSULATION RESISTANCE
HOW HVIR TEST WORKS ?
High Accuracy & Repeatability
Our HVIR Test Machine uses a PLC-controlled measurement system, high-quality voltage regulators, and industrial-grade measurement circuits to deliver highly accurate insulation resistance readings every time.
Automatic PASS/FAIL Detection
Our HVIR Test Machine uses predefined limits based on your product standards to evaluate every test outcome automatically.
Once the insulation resistance and leakage current values are measured, the PLC instantly classifies the appliance as:
-
PASS → Product moves to packaging
-
FAIL → Product moves to rework or rejection line
Digital Data Logging & Traceability
Our HVIR system captures every test cycle automatically and stores it in a secure database. This information can be exported or connected to your ERP, MES, or cloud dashboard through IT-OT integration.
Fast EOL Testing
Our automated HVIR system is optimized for high-speed, high-volume EOL environments, delivering complete insulation testing in just a few seconds. With automatic probe connection, rapid voltage ramp-up, and fast discharge cycles, the machine significantly reduces testing time per unit.
What is an HVIR Test Machine ?
The High Voltage Insulation Resistance (HVIR) Test Machine is a critical safety-testing system used to verify insulation strength in electrical appliances. It applies controlled high voltage and measures leakage current to ensure the appliance is safe for customer use.
Every appliance that contains motors, heaters, coils, compressors, or PCBs must undergo HVIR testing before packaging.
