Power quality refers to the quality of AC power supplied to users through the public grid. In general, it refers to the quality of the power in the power grid. Power quality problems are mainly caused by the terminal load side. For example, impulsive reactive loads will generate grid voltage. Dramatic fluctuations reduce the quality of power supply.
When the power quality of the power grid is disturbed or polluted and fails to meet the relevant national standards, the power quality of the power grid must be improved in a targeted manner. To understand the actual situation of the power quality of the power grid, it is necessary to have the corresponding equipment power quality analyzer ( It is also called a three-phase power quality analyzer) for testing and analysis.
Maintenance of power quality analyzer:
1. Battery maintenance and charging.
2. The instrument uses high-performance lithium-ion rechargeable batteries as the internal power supply. The operator cannot replace other types of batteries at will to avoid damage to the instrument due to incompatible levels.
3. The instrument must be charged in time. Avoid deep discharge of the battery to affect battery life.
4. Under normal use, charge it every day as much as possible (it is best to charge it once within a month if it is not used for a long time), so as not to affect the use and battery life. The charging time should be more than 6 hours each time. Because of the internal charging protection function, the instrument can be continuously charged.
5. Each time the battery is taken out of the instrument, the battery protection board inside the instrument automatically enters the protection state. After reloading the battery, it cannot work directly, and it can work normally only after powering on the charger to release the protection state.
