* Residual current is the difference between the current flowing into and out of a circuit . i . e . the difference is the amount of current leaking to earth .
Electricity : Spot that leak , monitor it to avoid costly shutdowns
Unfamiliar with the term leakage ( residual *) current ? This is the current that leaks to earth from live conductors and electrical equipment . Leakage current is an indicator of the health of an electrical system ( heartbeat / pulse ). Increases in leakage current indicate developing problems with the electrical system and or electrical equipment - an early warning ! Don ’ t wait for a fuse , circuit breaker to disconnect the electrical supply . You do not for example wait for pressure to exceed a critical level and shut down the production , you monitor it constantly . So why not monitor electrical leakage ?
Efficient and effective production is synonymous with the health of the production line . We monitor changes in temperature , vibration , pressure , sound etc to identify developing issues , 18 FDPP - www . fdpp . co . uk enabling earlier intervention . The cost benefits of monitoring leakage current , compared to the cost of lost production due to sudden power loss , damage to electrical equipment and personal safety are easy to quantify for individual sites .
Managing leakage currents
Electrical systems leak electricity to earth , this is a characteristic of electricity and electrical insulation . Leakage currents associated with electronic equipment such as speed
