DV/Dt -Reactor N CNW 806
Three-phase-dv/dt filter
Description
Reduce voltage rice to < 500V/µs – electrical consumers and insulation will protected with low costs.
A simple and inexpensive method for reducing the rate of voltage rise is to use a dv / dt filter or throttle. It dampens the voltage rise to acceptable values and prevents over voltages on long supply lines.
Losses and heating are minimized and the leakage current reduced. By limiting the rate of voltage rise, the motor insulation is protected and thus prolongs the life.
Also, the electromagnetic interference can be reduced in the radiation range of 1 MHz to 30 MHz.
Advantages
- Protection for electrical consumers
- Limitation of the voltage rise on <500V / us
