What's MOV?
Sep 29 , 2021
Metal oxide varistor (MOV) is a semiconductor element with unique grain boundary structure. Its resistance value decreases sharply with the increase of voltage. It has the advantages of excellent nonlinear volt-ampere characteristics, high current capacity, low residual voltage, no freewheeling and low cost. It has been preferred to be used in power supply and signal port as over-voltage pr...

Signal surge protection device protect instruments
Oct 14 , 2021
Electrostatic discharge (ESD) and electrical fast transient pulse group (EFT) will cause varying degrees of harm to instrumentation systems. Electrostatic discharge produces strong radio frequency radiation in the frequency range of 5 to 200 MHz. The peak of this radiated energy often occurs between 35MHz and 45MHz, and self-oscillation occurs. The resonant frequency of many informatio...

Silicon oxide varistor (SOV) surge arrester
Oct 27 , 2021
The traditional valve surge arrester was patented in 1935 and its basic design is a spark gap for overvoltage discharge, and a series resistor to limit freewheeling. This was the best design on the market for many years, but the silicon oxide varistor (SOV) surge arrester appeared now. The basic design of a silicon oxide varistor (SOV) surge arrester is a pair of metal electrodes sep...

Wind power-main force for carbon neutrality
Nov 11 , 2021
Wind power is the main energy source for constructing a new power system. It is the main force that supports the power system to take the lead in decarbonization, and then promotes the energy system and the whole society to achieve carbon neutrality. The large-scale and high-quality development of the wind power industry is an important strategic choice for implementing the dual-carbon...

Basic knowledge about grouding
Nov 23 , 2021
When a lightning wave hits a tower or lightning conductor, most of the lightning current will flow into the ground through the grounding device. If the grounding resistance is too high, the lightning current will generate a very high voltage on the top of the tower, causing the insulator to flash over and cause the line to trip. In recent years, power outages caused by lightning strikes have...
