MOTOR PROTECTION

TCI V1K dV/dT Filters Superior motor protection with V1K As Pulse Width Modulated (PWM) drives are incorporated into various applications and processes, the increased energy savings and decreased maintenance on VSDs can be offset by increases in motor failures. dV/dT filters limit peak voltage and increase voltage rise time in association with the output of VSDs. In addition to mitigating harmonics, the dV/dT filters also limit voltage spikes below 1,000V for long lead applications, reduce Common Mode Currents by 30% and significantly extend the life span of motors and cables.

The V1K product family has been designed as an engineered solution for motor failures due to the reflected wave phenomenon.

Voltage wave reflection is a function of the voltage rise time (dV/dT) and the length of the motor cables.

The impedance on either end of the cable run does not match and that causes voltage pulses to be reflected back in the direction from which it arrived. As these reflected waves encounter other waves, their values compound, causing higher peak voltages.

The V1K is the newest generation of dV/dT output filters from TCI and has demonstrated success in protecting the cable and motor insulation.

As cable length or carrier frequency increases, the overshoot peak voltage also increases. Peak voltages on a 460V system can reach 1200-1600V, causing a rapid breakdown of motor insulation which leads to motor failure.

Key Features: � Prevents voltage spikes from exceeding 1,000V up to 600m and limits dv/dt to less than 1,000V/μs � Increase the voltage rise time (dT out of dV/dT) � Slow pulse transitions, reduce dV/dT by a factor of 3 or more � The V1K has been used successfully in applications up to 914m depending on cable and VFD sizes � Protect motor and cable insulation � Greatly extends the life of the motor and cable � 30% reduction in common mode current � Reduces bearing currents and motor temperatures � Increase bearing life and up-time � Mitigates reflective waves � Available in IP00, IP20, and Nema 3R configuration.
