1. Regardless of whether the high-voltage or low-voltage equipment is powered or not, the personnel on duty are not allowed to move alone or cross the barriers and cordons to conduct any operation or inspection of the equipment.
2. When inspecting, pay attention to the safe distance: 0.6 meters in front of the high-voltage cabinet; 0.7 meters for 10KV and below.
3. Single people on duty are not allowed to participate in repair work.
4. After the electrical equipment has a power outage, even if it is an accidental power outage, you must not touch the equipment or enter the barrier before opening the relevant knife gates and taking safety measures to prevent sudden calls.
5. When inspecting and inspecting ground faults in rain, snow, or fog, you must wear insulating boots, and do not approach the lightning arrester during thunderstorms.

The fault point should not be approached within 4 meters indoors, and the fault point should not be approached within 8 meters outdoors.
6. After the phase-shifting capacitor bank is disconnected from the power supply, before the staff approaches the capacitor, regardless of whether the capacitor is equipped with a discharge device, it must be manually discharged with a portable special discharge load.
1: Double-click to quickly apply functions
There is no need to type the same function one by one. When you have set the function for the cells in the first row, just move the cursor to the lower right corner of the cell, wait until it turns into a small plus sign, double-click, and the formula will be applied to all the remaining cells in the column.

Isn’t this much easier than dragging with the mouse?!

For those of you who have to deal with Excel all day long, this trick may save you a little time. When you want to quickly insert a column, type Ctrl + Shift + '=' (Shift + '=' is actually the + sign) to insert a column to the left of the selected column, and Ctrl + '-' (minus sign) ) will delete the column you selected.
3: Multi-region joint calculation
In some worksheets, we do not need to sum continuous areas, but may be summing several discontinuous areas.
For example, there is a table that calculates the totals from January to February, March and May to June.
Enter the formula in cell H2, press the Enter key to complete and fill downwards.
=SUM(B2:C2,E2,G2)
