| Abstract/Contents: | Discusses potential methods of protecting sprinkler systems during a lightning storm. States that "developing surge protection in control products is one key element; however, following recommended grounding techniques during installation is equally important to ensure consistent product performance over a longer period of time." Suggests that "designing grounding circuits to protect electronic equipment is a scientific process that must be handled by qualified personnel." Recommends to "not use cheap electrodes"; "minimize the number of bends and sharp turns in ground wires and electrodes"; "never install grounding electrodes in the proximity of the wires...and cable connected to the electronic equipment as this could re-inject the lightning energy into the system." States that "the most important component of proper grounding is a circuit design based on sound engineering principles." Explains that "there have been several advances in...equipment...including adding larger metal-oxide varistors (MOVs) on both input and output lines. Designed to respond to the speed at which surges reach their peak current, MOVs quickly clamp the initial energy spike when it exceeds a safe level. The larger the MOV, the more effective the response." Explains that "installing a hydraulic system used to be the best way to protect valve-in-head sprinklers from being damaged during lightning storms; however, this is no longer the case. By enhancing the solenoids with surge protection, system components beyond the controller are being protected in even the most high-risk areas of the [United States]." |
