WVR-TSC (Wide Voltage Range-Total Surge Cancellation) is truly remarkable technology since it entirely eliminates damaging surge energy from protected equipment, not merely suppresses the surge to a lower value (WVR US patent 6,728,089, TSC US patent 7,068,487).

Surge frequencies are in the 1,000 Hertz region and higher, while the power frequency is only 60 Hertz.  With this wide frequency difference, it is relatively easy to filter off the undesired surge frequencies and noise.  WVR-TSC does this.  It first filters off the most dangerous surge frequencies, and then it cancels the remaining residual surge voltage.

Refer to the simplified schematic below.

A surge enters at point A.

The transformer cancelling winding immediately begins to develop a cancelling voltage due to the surge current flow in the transformer primary winding.

The surge is filtered and delayed by the transformer primary inductance and the capacitor, with only some residual low frequency surge components appearing at point B, but delayed in time due to the filtering action.

The cancelling voltage from the transformer is added to the point B filtered surge.

Adding the cancelling voltage to the delayed residual surge voltage prevents even the residual surge voltage from exceeding the power wave peak voltage, reducing the surge voltage let-through to zero! (Refer to the comparison page).

Since WVR-TSC uses non-sacrificial filter components, the service life is at least 10 years.
