| dc.description.abstract | Small and medium-sized industrial control panel makers, systems integrators, and repair shops frequently encounter issues with Variable Frequency Drive (VFD) testing. These companies frequently rely on third parties to evaluate their VFDs prior to field commissioning, increasing expenses. To address this issue, an in-house test bench was created for a control systems integrator's maintenance department (KJ Controls). The test technique includes static, functional, and operational testing of the drive under test. To completely verify the VFD's operational capability, it must be connected to a loaded motor. A load motor/dynamometer is required for this test. For this, a prototype was created in the repair department using readily available and stock components. This configuration facilitated the testing of the operation and functioning of a 2 HP drive. The tests run on the drive included a static test, a free run test, a motor stall test, and a speed regulation test. These were then suitably recorded on a factory acceptance test sheet. It was eventually calculated that having an in-house testing system would save the company at least 10% on the total cost of testing repaired VFDs. It was predicted that the payback period for such a test bench arrangement would be close to three years. | |
