LV & MV Load Bank

Thomson Power Systems Resistive Test Load Banks utilize coiled chromium alloy load elements supported with cool cast ceramic insulators. All load resistor ends are fitted with silver soldered stainless steel connection studs. Thomson’s “cool load®” resistor design guarantees lower operating temperatures and extended life in the most adverse environments. Each “cool load®” resistor is mounted in removable load resistor frames. Load resistor frames are designed for dual pass “cool load®” resistors. Removable racks and dual pass “cool load®” resistors provide superior serviceability and reliability. 

Five standard load resistor frames are used in a single or stacked configuration for load banks from 80kW - 1100kW. Custom load resistor frames are available for fan cooled load banks. Integral, direct drive, single or three phase cooling fans provide up to 25,000CFM per load bank. Adjustable temperatur and air flow sensors are provided to guarantee safety shutdown in case of airflow failure. 

Load bank control compartments are located in a heat resistant compartment. Control components include load stepping contactors, load step selector switches and fault indicators. Optional features include AC metering, integral over current protection and automatic load step control.
