The problem that ZAP exists: the 1) uncertain problem of decipherment distance: the different periods for the same line road can receive carrier signal sometimes; Sometimes but can't receive; Its main cause is that the different period users of low voltage electric network are different to the intensity of the noise of electrical network generation; The line impedance that different period user load differences cause is different; Thereby cause the serious decay of carrier signal, long-distance transmissions that can't be stable makes and can't reliable and stable discern based on the platform district identifier of carrier communication principle; 2) identification accuracy problem: for platform district transformer altogether high pressure, altogether, there is the problem of accuracy in the platform district identification of adjacent many distribution transformings of cable trough altogether; Because the platform district identifier of carrier wave principle only adopts power carrier signal to carry out User Recognition; And being high-frequency signal, carrier signal can be coupled to the 10kV high-pressure side through distribution transformer; Be transferred to adjacent distribution transforming through the 10kV high-voltage line again; ZAP can't distinguished the mutually same of this distribution transforming and adjacent distribution transforming, thereby causes " getting lines crossed " phenomenon, both " high pressure is being got lines crossed altogether "; In like manner if adjacent distribution transforming has common ground situation, carrier signal equally also can got lines crossed to adjacent distribution transforming, promptly " gets lines crossed altogether "; If the low-voltage cable of adjacent distribution transforming is walked same cable trough, carrier signal can be gone here and there in other distribution transforming both " cable trough is being got lines crossed altogether " through the capacitive coupling between cable.
Specific big pulse current technology is to discern through the pulse current of specifying a 50A or 100A.
Adopt the weak point of specific big pulse current technology to have, pulse current may cause damages, can cause interferences, this technology because of having only a pulse signal to cause dropout easily to detection line simultaneously too greatly equipment, cause discerning less than.
