Overload Monitoring

Overload monitoring models are used to ensure Infeed Modules, Bleeder Modules, Energy Storage Modules (ESM), Inverters and Motors do not overheat when in an overload condition (application value > continuous rated value) for a prolonged duration. The continuous power and rms current and torque values cover most conditions. However, if the cycle time is very long, the rms and average values can be minimized. The Overload Monitoring accounts for this situation, by applying an exponentially weighted time factor to the overload value (utilization factor, U).

Sample Scenario: Inverter Ixt
Infeed Pxt & Inverter Ixt
Bleeder Bxt
Energy Storage Module I2t
Motor I2t
