Explain difference between AIS and GIS. MV switchgear is an important part of power distribution system for maintaining the continuity of service, and you have to consider some different aspects based on your needs before selecting a suitable MV switchgear.
What is ACR Auto Recloser? Auto recloser (ACR) also named automatic circuit recloser is recognized by electric utilities throughout the world as an essential device for achieving their prime goal: providing maximum continuity of electric service to customers.
Difference Between DC Charging and AC Charging. AC charging has lower power, requires longer charging time, but has less loss to the battery. On the contrary, DC charging pile has higher charging power, faster charging, but has greater loss to the battery.
What is Distance Protection Relay? Distance protection relay is the name given to the protection, whose action depends on the distance of the feeding point to the fault. The time of operation of such protection is a function of the ratio of voltage and current, i.e., impedance.

Many people are confused about the difference of power transformer and distribution transformer. In fact, there are many difference between them, and this article will help you fully understand their differences.
Rural power grid transformation and upgrading refers to the new construction of rural power grid facilities such as substations and lines, as well as the local or overall local or remote construction, capacity increase and equipment replacement of existing rural power grid facilities.
Application Reason of Step Voltage Regulators: The voltage on modern distribution circuits is becoming increasing difficult to manage. New distributed energy resources, such as solar, combined with the growth of sophisticated loads creates voltage challenges on distribution network systems. Existing voltage control devices cannot maintain a consistent voltage profile.
The indoor SF6 load break switch is a kind of switching device with a simple arc extinguishing device which is installed in ring main unit and switchgear. It can be used for switching and breaking load current and overload current.
RPS type SF6 load break switch (SF6 LBS) is a pole-mounted load beaker switch independently developed by Wenzhou Rockwill Electric Co., Ltd. It is suitable for load current, overload current breaking and closing in a voltage range of 11~40.5kV distribution network ,also can automatically isolate faulty distribution lines.
At present, most enterprises are connected to the power grid by using 33kV box type prefabricated compact substation built by themselves.
