Operation
Transient Voltage Filters
TVFs are applied to circuits where transient electrical voltage spikes can cause a malfunction or damage in solid state controls or control systems (PLCs, CNCs, NCs, Solid State Counters, etc.). The TFD is typically applied in parallel with three phase inductive loads (motors) to absorb the transients generated when the load is disconnected from the line. It also absorbs electrical noise while the load is operating. The Bleeding Resistor allows the voltage that builds up on the capacitor in the TFD to bleed off after voltage is removed. The Bleeding Resistor is typically used in applications where the control with the TFD may be operated (tested) without the load (motor) connected.
