Surge Protective Devices (SPDs) are used to limit the impact of lightning, grid switching and other transient overvoltages on electrical equipment. Since SPD is exposed to varying degrees of surge cur

For electrical engineers, mastering the basic professional knowledge of Surge Protective Devices is the core basis for electrical system design, construction, operation, and maintenance. The essential

When a voltage surge invades an electrical circuit, the SPD completes the whole protection process of response, conduction, discharge, voltage clamping, and reset in microseconds, with the specific wo

Solar PV systems are highly exposed to lightning-induced surges due to large outdoor PV arrays and long DC cabling. Unlike AC systems, PV DC circuits have no voltage zero-crossing point, so improper S

DP Current Transformer is an important equipment for current measurement relay protection and energy monitoring in power system. The installation quality not only affects the accuracy of measurement d

Surge protector is an important protection device against lightning strikes and transient overvoltage damage in power system. After SPD is installed, many users will have a question: Do surge protecto

With the rapid development of the global photovoltaic industry, more and more residential, commercial, industrial and utility scale power plants are adopting solar power generation systems. However, P

With the rapid development of the global new energy industry, photovoltaic (PV) has become a widely used clean energy solution for enterprises, industrial parks, commercial buildings and residential c

With the rapid development of industrial automation, intelligent building, new energy generation and data center construction, electrical equipment requires more and more power quality and operation s

1.Verify DP Current Transformer Model Parameters Before Installation Before installing the DP Current Transformer, verify that the device type, rated current, transformation ratio, accuracy rating, an

1. Prolonged Overload Operation One of the most common causes of DP current transformer overheating is overload operation time. When the actual operating current exceeds the transformer's rated cu

The fault detection and solution of DP Current Transformer (such as open, closed or high precision transformer) needs to be carried out systematic investigation and localization according to the struc
