Another feature that bolsters the Perfect Harmony's reliability is its control strategy. Our Process Tolerant Protection Strategy (ProToPS™) is a groundbreaking process control system available exclusively from NELCO. Instead of tripping the drive and automatically shutting down the system due to a malfunction, ProToPS provides a hierarchical system of warnings. This control strategy allows time to evaluate the situation and respond appropriately to avoid a system shutdown. ProToPS has proved invaluable for many of our Perfect Harmony customers, including strategic power plants, refineries, water and wastewater facilities, and process plants.
Upon delivery, you can be confident that the Perfect Harmony will get your process running because we have the ability to test every product as a complete system at full load. At our factory, we test every transformer and power converter together so that any imperfections can be identified and corrected before the product is shipped. In addition, factory testing allows accurate efficiency measurements. We also verify sequence of operation and protection to ensure that the Perfect Harmony system matches your needs.

Protecting Process Quality
If a power cell is bypassed, there is minimal degradation of the motor's output power quality, as the Perfect Harmony's advanced power cell bypass system ensures that your process is uninterrupted.
