According to transformer aging mechanism and referring to relevant studies at home and abroad, the paper evaluates the aging and residual life of 330kV power transformer by means of measuring the degree of polymerization (DP) of insulation paperboard. The result shows that DP of power transformer...
How Does a Conventional Transformer Work? The operation of a conventional transformer is based on the principle of electromagnetic induction. When an alternating current (AC) flows through the primary winding, it creates a magnetic field that induces a voltage in the secondary winding. The voltage ...

By utilizing the mobile substation as a replacement for the equipment undergoing maintenance, the affected circuit (such as a line, transformer, or generating unit) can continue to operate for a significant portion of the work. This procedure is best suited for mid- and long-term projects, ...
Short circuit protection: In the stall experiment, the equipment may generate huge currents due to overload or stall. It is important to choose fuses with lower melting current and fast melting characteristics to prevent equipment from overheating or damage. Freeze voltage: Select the fuse according...
Sometimes people think that a summer power outage is easier to deal with than a winter one. After all, in the summer, you don’t have to worry about freezing to death, which is a very real threat during a long-lasting winter outage. ...
That would certainly be true if we made all our energy from one, single mega-sized wind turbine—but we don't! In reality, even countries that have large supplies of wind energy have plenty of other sources of power too; as long as wind power is making less than half of a country's...
•How long does a Power Bank last? This is a bit of a loaded question. There are two important life expectancies to consider: 1. The number of charge/discharge cycles a Power Bank can reliably perform in its lifetime. 2. How long a Power Bank can retain its charge when not in use...
I am not sure what model of Oral-B you have currently or how long you have had it, but I am surprised by your suggestion that the Pro 1000 and Smart 1500 you have tried were rougher and louder. Most Oral-B models are configured the same way and offer the same brushing action and ...
Older nickel-cadmium battery technologies required their owners to fully discharge (use them until they are dead) them before recharging them, however, lithium-ion batteries are the opposite. Their lifespan (as in, how long they last before they malfunction and need replacement) decreases as you...
