WF系列节电器可有效抑制瞬变和浪涌的幅度，起到明显的节电效果。
WF SERIESE can control the range of the transient and surge efficiently to save the electricity apparently.
瞬变和浪涌是正弦交流波电路上电压与电流的一种瞬时态的畸变。浪涌、谐波为主要的表现形式。
Transient and surge are the instant aberrance of the voltage and electric current on the simple alternating current wave circuit. surge and harmonic wave are the main manifestation.
