Principle of operation The widespread acceptance of personal computers and the reasonable price of the equipment makes it Realistic to create test equipment for laboratory and production purposes that are simply user-interfaces to such PCs. In so doing, the power of a local computer such as that for calculation purposes, program and data storage, file handling, application-orientated screen presentations, print-outs of protocols and lists, networking and communications possibilities with other parts of the plant, etc. can be made available to a test rig and its operation. Such a concept demands that the test equipment itself incorporates the necessary processor intelligence in order to be able to carry out all the specific tasks and real-time procedures and to be able to understand the PC Software as an integral part of the product. The NSG 650 Generator contains a high performance microprocessor as the controlling element. This controls and monitors all the functions of the instrument, regulates the time-dependent generation of the pulses, secures and checks the statuses of switching elements, collects the results of the measurements taken and constantly monitors the safety elements in the test set-up. In addition, the microprocessor handles the communications through the computer port together with other inputs and outputs as well as checking all the entries for validity and plausibility. As can be seen from the block diagram, the energy part of the instrument is made up of several sub-systems as described below. A mains-driven power unit supplies both the control section and the high voltage Generator with stabilised dc. The zero-crossing detector produces reference signals so that the pulses can be superimposed on the mains supply to the EUT at the programmed phase angle. Safety circuits combine and interlock the status signals from the key-switch, the microprocessor, coupler and external protective gear to ensure that the demand for 'safety first' is met under all operating situations and abnormal conditions, The high voltage supply charges the capacitors in the discharge network to the required voltage and then ensures that a constant charge is maintained until a pulse is triggered.
