In recent years, with the deepening of reform and opening-up, electrical instrumentation engineering has driven rapid industrial development and plays a vital role in promoting industrial transformation.Currently, technological upgrading has become a key initiative for enterprise revitalization. Whether it invol

Analysis of Measurement Errors in Electrical Instruments and Elimination Strategies1.Electrical Instruments and Common Testing MethodsElectrical instruments play a vital role in the generation, transmission, and utilization of electricity. As a special form of energy, electricity requires strict safety standards in production and use. Safe electricity usage is crucial to daily life, production, and socio-economic development. Power system monitoring relies on electrical instruments, which are of

The 10kV high-voltage reactive power compensation device is an essential and indispensable component in modern power systems. By providing or absorbing reactive power, it effectively addresses issues such as low power factor, high line losses, and voltage fluctuations caused by reactive power demand, playing a key role in improving the economy, safety, and power quality of grid operation. High-voltage 10kV reactive power compensation is a critical device for ensuring safe and economical grid ope

The test site layout must be reasonable and organized. High-voltage testing equipment should be placed close to the test object, live parts must be isolated from each other, and remain within the clear line of sight of test personnel. Operational procedures must be rigorous and systematic. Unless otherwise specified, voltage must not be suddenly applied or removed during operation. In case of abnormal conditions, voltage increase must be stopped immediately, pressure rapidly reduced, power disc

In modern power systems and materials science research, ice coating test chambers have become increasingly indispensable.These chambers simulate complex climatic conditions such as rain, snow, freezing rain, and ice formation, providing reliable data support for scientific research, production, and quality inspection.As energy transition progresses and power transmission networks expand, the diverse applications of ice coating test chambers are becoming ever more prominent.What Is an Ice Coating

1.Shortcomings of Existing Temperature Online Monitoring Products1.1 Temperature Controller for Dry-Type Transformer Winding MonitoringPlatinum resistance sensors are used in temperature controllers. Since they lack insulation, the sensor must be disconnected from the controller during withstand voltage tests. However, overvoltage during actual operation often damages the controller. Additionally, the sensor's lead wires cannot withstand the 350°C high temperature required for thermal and dynami

Role and Selection of Microcomputer Integrated Protection Devices in High-Voltage SwitchgearIn recent years, the application of microcomputer integrated protection devices in medium- and high-voltage power distribution system projects has increased significantly. These devices are user-friendly and overcome the drawbacks of traditional relay protection, such as complex wiring, low reliability, and cumbersome setting and debugging procedures. Microcomputer integrated protection devices feature co

What is a microcomputer protection device?Answer: A microcomputer protection device is an automatic device that can detect faults or abnormal operating conditions in electrical equipment within a power system, and act to trip circuit breakers or issue alarm signals.What are the basic functions of microcomputer protection?Answer: Automatically, rapidly, and selectively isolate faulty equipment from the system by tripping circuit breakers, ensuring non-faulty equipment resumes normal operation qui

Retrofitting microcomputer protection devices in substations should follow specific steps and precautions. A possible retrofit plan is as follows: Investigate the current status: Understand the types, specifications, operating conditions, and existing issues of the microcomputer protection devices in the substation to provide a basis for the retrofit. Develop a retrofit plan: Based on the investigation and requirements, create a detailed plan including specific tasks, technical specifications, i
