Current clamp saturate, it can be made flexible, and does not require any magnetic or electrical contact at the opening end. The Rogowski coil gives a voltage proportional to the rate of change of current in the primary cable, so more signal processing is needed before the sensed values can be displayed. An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of
Electrical Artificer Electrical Artificer An Electrical Artificer (EA) is an electrical technician competent in the electrical maintenance of ship's machinery such as engines and generators. This was originally a Royal Navy term for those trained and competent in the installation and maintenance of ships electrical systems. The title has been replaced in the Royal Navy . However the Irish Naval Service continues to use the term 'Electrical Artificer' (EA) for electrical technicians. A distinctive propeller insignia is worn to identify these personnel. Training is completed in the National Maritime College which is incorporated into the Cork Institute of Technology. Prior to its
