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
Special measures the action plan has been completed and all points satisfactorily addressed, then they will refer the school back to Ofsted and ask them to schedule a second Section 5 Inspection. If Ofsted agree with HMI’s judgement, the school is then removed from the special measures category. It is worth noting that during an Inspection an HMI can change the nature of the Inspection to a Section 5, and remove the school from Special Measures upon completion. Support for schools that enter special measures comes in a variety of forms, and varies from local authority to local authority. Typically though schools
