HZJF-9104 Four Channels PD Partial Discharge Detector
Partial Discharge Detector for 4-channel, desktop, TFT liquid crystal display, reliable system, low failure rate. In addition, it can be used for the local discharge measurement of high voltage electrical equipment (standard), it also has the function of accurate positioning of the fault points of the faulty equipment (optional), and can also be used for the online continuous monitoring of the local discharge of high voltage electrical equipment such as large power transformers (optional). Truly realized the bureau put measurement, positioning, online monitoring multifunctional into one.
This Partial Discharge Detector is the dedicated product to measure and analyze the insulation ability of electrical equipment. This system adopts modern electronic and computer integrated technology with the functions of signal amplification(analog signal, electronic signal, digital signal), filtration, data sampling, data processing, figure display, test report generation automatically so that it may finish the measurement, location and analysis of the partial discharge.
The discharge device applicable scope, test method, test circuit, technical performance parameters fully meet the national standard, the international standard IEC60270-2000 GB7354-2003 "measurement of partial discharge (Partial Discharge measurements)" and "requirements" guidelines for the measurement of partial discharge of power equipment DL 417-2006 standard field.
