<p>The power measurement system is designed for use with a multi output distributor unit. Each output has an instantaneous intensity detector, and a wattmetric convertor. The convertor is designed to produce from analogue electric signals from the detector a signal representing instantaneous power on a connected output. The signals are transmitted via an analogue digital convertor to a recording system. Switching circuits connect the wattmetric convertor to detectors associated with the outputs. A sequencer system triggers a regular time intervals, a measurement cycle. During the cycle the wattmetric convertor is successively connected to detectors associated with all the outputs. The power is transformed into digital data and recorded.</p> |
