Primary injection test procedure pdf

11.Injection. Starts current injection and timing. 12.Momentary Injection. When this button is used, injection continues only as long as it is pressed. Useful in order to avoid for example overheating. 13.RS232 for computer. ODEN AT is equipped with a serial port for communication with PC (for transfer of test data for ex-ample). 14.Manual shut In the ratio test, the ratio test in the CT is performed by connecting the CT primary to the current source, find out more bit.ly/2UAcHW0 Website: ht Primary injection in power transformers is sometimes called a "through-fault" or "thru-fault" test. Essentially, a three-phase source of sufficient voltage, current, and volt-ampere rating is connected to a short-circuited transformer to supply current through the windings. The CT circuits are then checked for current magnitude and phase Multifunctional Primary Testing System The Raptor is a smart test system designed as the ultimate solution for the main primary test applications required in the commissioning and maintenance of substations, marking the difference with respect to existing equipment now being used. This new generation of Primary Injection Test System makes primary SKU: BH-32412. Programma ODEN A/2S 240V Primary Current Injection Test System - The Programma ODEN A system consists of a control unit together with one or two current units (1 = Number of current units). All parts are portable, and Programma ODEN A can be quickly assembled and connected.
