What are the reference standards for detecting surge protective devices? What are the detection methods? According to relevant testing standards, the Baijian Testing Center conducts inspection and testing on the nominal voltage, rated voltage, rated discharge current, maximum discharge current, and other items of samples including switch type protectors, voltage limiting protectors, and shunt protectors. Generally, a report is issued within 7-15 working days! Detection scope: switch type protector, voltage limiting protector, shunt protector, choke type protector, shunt protector, choke type protector, power supply protector, AC power supply protector, DC power supply protector, switch power supply protector, signal protector: low-frequency signal protector, high-frequency signal protector, antenna feeder protector, etc. Test items: nominal voltage, rated voltage, rated discharge current, maximum discharge current, voltage protection level, response time, data transmission rate, insertion loss, echo loss, maximum longitudinal discharge current, maximum transverse discharge current, online impedance, peak discharge current, leakage current, etc. According to testing standards: QX/T 86-2007 Technical Specification for Testing Surge Protectors in Operation QX 10.1-2002 Surge Protectors Part 1: Performance Requirements and Test Methods QX/T 108-2009 Surge Protectors Test Methods NB/T 31040-2012 Surge Protectors with Short Circuit Protection Function CB/T 4171-2011 Marine Low Voltage Surge Protectors GB/T 18802.22-2008 Low Voltage Surge Protectors Part 22: Surge Protectors (SPDs) for Telecommunications and Signal Networks Guidelines for Selection and Use of Surge Protectors QX/T 10.2-2007- Part 2: Principles for Selection and Use in Low Voltage Electrical Systems JB/T 10618-2006 Combined Surge Protectors (Boxes) DL/T 5408-2009 Specification for Configuration, Installation, and Acceptance of Surge Protectors for 220/380V Power Supplies in Electronic Information Systems of Power Plants and Substations
