TDI Load Bank Solutions for Reliable Generator and Power System Testing

TDI load banks are engineered to deliver precise, repeatable power system testing across industrial, commercial, and utility environments. Whether you're conducting factory acceptance tests (FAT) for new generators or validating backup systems in data centers, TDI’s resistive, reactive, and combination load bank solutions ensure accurate simulation of real-world electrical loads. These devices mimic the full spectrum of load conditions—steady-state, transient, and harmonic—to verify generator performance, stability, and compliance with IEC 60348 and IEEE 1547 standards. A typical TDI resistive load bank can handle up to 2,000 kW at 480 VAC three-phase, with a power factor adjustment range from 0.1 to 1.0, allowing users to test both leading and lagging power factors. Their active cooling systems—including forced air and water-cooled options—enable continuous operation under high thermal stress, while built-in digital controllers offer remote monitoring via Modbus TCP or RS-485 interfaces. Safety features like overtemperature protection, E-STOP buttons, and CE/UL certification make them suitable for use in demanding applications such as wind farm grid integration or hospital emergency power systems. For portable testing, models like the TDI 500kW mobile load bank are equipped with fork-lift pockets and lifting eyes for easy transport. Regular calibration (every 12 months) and maintenance of resistor blocks and fans ensure long-term accuracy and reliability. An anonymized case study from a U.S. utility company showed that using a TDI RLC load bank reduced commissioning time by 30% during a 12-month microgrid project by enabling faster validation of voltage regulation and frequency response under varying load profiles.
