Lightning protection methods: an update and a discredited system vindicated

The end may be near for the two hundred year old method of using a Franklin rod to collect, control and convey to earth the awesome and destructive power of lightning. The side effects of allowing thousands of amperes to flow adjacent to and near computers and sensitive electronic equipment can be considered foolhardy and costly. The Charge Transfer System of preventing lightning strikes to protected areas is a valid concept and will replace the Franklin rod method in many applications. The changes that are occurring with lightning protection technology include the renewed debate over sharp pointed versus blunt rods. The advent of a method for the detection and measuring the magnitude of lightning strikes is replacing the old isokeraunic level charts. Promulgation of a standard for early streamer emission, prevented by what can be considered as an act of restraint of trade, has resulted in legal action being taken against the National Fire Protection Association and others.
