Product Introduction Digital PD Detector Partial Discharge Testing Digital PD Detector Partial Discharge Testing Product Overview The transformer partial discharge detection device and the sensorwith the software using advanced signal processing technology covering a wide range of statistical methods and graphical display mode and coming with highenergy lithium batteries can flexibly achieve the detection of transformer partial discharge signals and ultrasonic signals capable of full range of detection for the transformer's partial discharge. Partial discharge detection location detect the partial discharge changes in the transformer's internal during the operation by examining the partial discharge conditions of the device to analyze the insulating state of the transformer. High frequency current transformers (pulsed current method) an ultrasonic sensor (ultrasonic method). Through a variety of means to suppress various external noise interference it improved signal to noise ratio and the measurement accuracy. product features Product Characteristics Digital PD Detector Partial Discharge Testing Working Condition Altitude 3000m Environmental Temperature -20~60C Relative Humidity 95%
