1. Visually inspect the UPS and battery (or other energy storage) equipment for obstacles, and properly cool the surrounding area.
2. Ensure that there is no abnormal operation or positive warning on the UPS panel, such as: overload or overdischarge of the battery close to it.
3. Check whether there are traces of battery corrosion or other shortcomings.
4. Consult the manufacturer's equipment guidelines and claims. You should perform protection (or hire a professional to do so), as the manufacturer claims, often or at least in some cases, and of course, the more often you look at it, the better.
5. Recognize that UPS components will cause problems. This seems obvious: any probability of a problem will eventually go wrong. Critical UPS components, such as batteries and capacitors, wear out in normal use, so even if your utility is perfectly powered, your UPS room is thoroughly clean, and everything is working perfectly at the right temperature, the components will still fail. Your UPS system still needs to be protected.
6. Know who to call when you need service or repair from time to time. During the daily or weekly viewing period, there may be problems, and it may not be possible to wait until the next scheduled protection. In this case, knowing who to call can greatly reduce stress. That said, it's important to identify solid service providers who can provide services when you need them. If you maintain an excellent repair record in the same location as your UPS, you will be able to provide useful information when the supplier arrives, potentially saving you a lot of service time and service costs.
7. Assign tasks. "Shouldn't you have checked last week?" "No, I think you should go." Avoid this mess: When it comes to UPS protection, make sure the right people know what they are responsible for.

The reason why the circuit breakers of multiple stages trip together is Delta
Short-circuit maintenance (overload maintenance) is an important function of circuit breakers, and the reason why this function is achieved is that the circuit breaker senses the temperature in the circuit through a thermal iron plate. Once the temperature in the circuit is too high, it is transmitted to the mechanical mechanism in the circuit breaker for trip maintenance.

Problems in the inverter application – Delta inverters
1. Harmonic problems
The equipment that plays the role of switching in the main circuit of the inverter must generate harmonics in the process of turning on and off the circuit. The lower harmonics generally have a greater impact on the motor load and cause torque ripple; The higher harmonics increase the leakage current of the inverter's output cable, making ...
