Isolating spark gaps or protective spark gaps are supposed to establish a galvanic isolation of electric parts of the installation, which are not connected with each other under normal operating conditions.
- Specific applications:• for establishing a galvanic isolation of insulating
flanges and insulated couplings (e.g. fuel pipes) • Cathodic corrosion protection of tanks• Cathodic corrosion protection of pipelines• Lightning equipotential bonding of gas pressure regulation stations
Assembly:Isolating spark gaps can be mounted between the parts of the installation to be bridged by means of brackets or connectors. When mounting isolating sparks, the shortest possible cable length should be used as long cables increase the danger of inductive voltages putting unnecessary stress on the isolation.
