The Smart-Gap improves the performance and reliability of power line carrier communications by minimizing the impact of any surge-induced loss of carrier signal, also known as carrier holes. The Smart-Gap operates faster than traditional spark-gap solutions, extinguishing surges in less than 0.5 msec. to minimize any signal loss.
The maintenance-free Smart Gap is an ideal replacement for gas discharge-tube or airgap protection, which require regular maintenance. The Smart Gap’s compact size provides an easy retrofit into existing line tuners and coupling capacitor voltage transformers (CCVTs).
Communication interruptions can cause miss-operations in protective relay systems resulting in over trips on DCB (blocking) systems, delayed trips in POTT or DTT systems, or false permission to trip in DCUB (unblock) systems. The patent pending Smart-Gap product prevents the impact of these carrier holes by quickly clearing the surge to minimize any communication interruption.
FEATURES AND BENEFITS:
• Fast clearing – less than 0.5 msec.
• Significantly reduces carrier holes
• Retrofits existing spark gap
• Improves carrier communication reliability
• Robust design – maintenance free
