For optimum protection from surges and noise, the goal is to keep the surge energy from exceeding the normal power wave region. As the surge energy travels, the sudden rise of voltage (dV/dt) and current (dI/dt) is what causes the degradation of sensitive electronics. We will show you how Series Mode Filter Technology compares to MOV products while being subjected to surge energy. The following actual oscillograms dramatically demonstrate the superior surge suppression of WVR filters when compared with conventional surge protectors.
Using an oscilloscope, one can look at the voltage as it changes in real time and take a snap shot. To catch the surge as it travels through the test circuit, the oscilloscope triggers the probe measurement to take place during a window of time while the surge is passing by. North American 120 volt power oscillates between +170 and -170 volts. We call the power to have 120 volts because it is the peak voltage divided by the square root of 2 (170 / 1.414 ≈ 120). The time it takes to complete one cycle is 1/60 of a second because power oscillates at 60 Hz. There are 16,667 microseconds in one cycle. Surges happen within one cycle. The standard IEEE C62.41 test surge is a combination wave of energy of 6000 volts / 3000 amps that lasts 50 microseconds.
Zero Surge Product – the following tests were performed using our 15 amp products. The other current rated products perform in the same manner with the same type of results relative to their rated current.
Competition – a typical plug in MOV protector and a whole building MOV protector are tested.
