In the context of frequent lightning disasters, lightning protection testing, as a core link to ensure the safe operation of buildings, power systems, and communication facilities, directly affects the reliability of lightning protection engineering in terms of technical standards and equipment performance. Shanghai Shenggao Electric Technology Co., Ltd., with its independently developed Class B lightning protection detection equipment, provides a one-stop solution for the industry through high-precision sensors, intelligent data acquisition, and compliance design, promoting the upgrading of lightning protection detection towards digitalization and standardization.

1、 Technical core: detection capability with full scene coverage

Shenggao Class B lightning protection detection equipmentGB/T 21431-2015Based on the Technical Specification for Testing Lightning Protection Devices in Buildings, it covers grounding resistance, equipotential bondingSPDperformance, etc.19Key detection indicators, forming coverage“External lightning protection-Internal lightning protection-SPDprotection”Full chain detection capability. Its core equipment, such asSG3050Equipotential tester, using four wire measurement technology, with a resistance measurement resolution of up to0.001ΩIt can accurately detect the quality of equipotential bonding between metal components, avoiding the risk of lightning strikes caused by excessive contact resistance.

In the field of soil resistivity detection,SG3001EThe soil resistivity tester is installed using the quadrupole method and can maintain its stability even under complex geological conditions such as rock layers and frozen soil layers±2%The measurement accuracy provides reliable data support for the design of grounding grids. And regardingSPD(Surge protector) detection,SHSG9200The lightning protection component tester can automatically complete the testing of pressure-sensitive voltage, leakage current, and current carrying capacity, supporting data storage and traceability analysis, greatly reducing the time requiredSPDScreening cycle.

2、 Product Innovation: Dual Breakthrough of Intelligence and Portability

Shenggao Electric integrates IoT technology into traditional detection equipment to create“detection-analyze-report”Integrated platform. For example,SGDW-5AThe ground network tester is equipped with a built-in variable frequency power module, and the output frequency can be within45Hz/55HzInter switching effectively avoids power frequency interference and ensures the stability of measurement data in strong electromagnetic environments such as substations and chemical plants. It is equipped with7The inch touch screen can display a real-time three-dimensional grounding impedance distribution map, assisting detection personnel in quickly locating the fault point.

In terms of portability design,SG3010The weight of the grounding resistance tester is only1.2kgSupports Bluetooth data transmission, and detection personnel can use their mobile phones for testingAPPReal time uploading of data to cloud platform for parallel management of multiple projects. In addition, the equipment comes standard with explosion-proof intercoms（GP328）Combustible gas tester（BH-90）To provide safety guarantees for high-risk scenarios such as petrochemicals and gas, and to avoid secondary disasters caused by operations.

3、 Industry application: Upgrading from compliance detection to risk warning

Shenggao Class B lightning protection detection equipment has been widely used in fields such as energy, transportation, and communication. In a substation renovation project of a provincial power grid, its ground grid tester detected that the corrosion rate of the grounding grid exceeded30%Guide the construction unit to accurately replace the grounding electrode in the designated area to avoid equipment damage caused by lightning strikes. In the acceptance of a lightning protection project in a data center, the equipotential tester found that there were issues with the metal cabinet and grounding system in the computer room0.5ΩThe potential difference was rectified in a timely manner, and the electromagnetic pulse caused by lightning was eliminated（LEMP）Interference risk.

To further expand the value of equipment, Shenggao Electric has launched“Lightning protection detection digital twin system”By deploying sensors at critical nodes of buildings, real-time monitoring can be achievedSPDConstruct a lightning risk warning model based on parameters such as degradation degree and changes in grounding resistance, combined with meteorological data and historical lightning strike records. The system has been piloted and applied in a chemical industrial park, successfully providing early warning3Potential lightning accidents have occurred, reducing economic losses by over ten million yuan.

4、 Compliance assurance: Building a full lifecycle service system

Shenggao Electric's Class B lightning protection detection equipment has passedCMATheCNASCertified and equipped with a built-in measurement traceability module to ensure that the testing data meets the requirements of the "Management Measures for Lightning Protection Device Testing Qualifications". The company also provides“equipment+training+certification”One stop service for testing personnelISO 17025Quality management system training to enhance operational standardization and report preparation capabilities. At present, its equipment has assisted the whole country200Yujia testing institutions have obtained Class B qualifications, promoting the standardized development of the lightning protection testing market.
