TOTAL EVALUATION OF AN INVERTER-CONTROLLED ELEVATOR

PZ4000 can make a total evaluation of an inverter-controlled elevator. The figure1 below shows an example of a evaluation connection to an inverter-controlled high-speed gearless elevator. PZ4000 captures motor voltage, current and 3-phase power supply in total series of actions from the start to stop, as shown in the Graph1. Furthermore, it can calculate power values and related parameters in a specific period. Although current signal is controlled to form a sine wave, various functions of PZ4000 works great to measure harmonic components and calculate the total power factor.
