Why does the power factor need to be corrected at MV?

Reactive power compensation is essential for the correct technical and economical management of an MV Networks. Its benefits are:

Economic benefits

— Reduced billable reactive energy costs (surcharges by country and tariff)
— Reduced hidden economic cost from the Joule effect in transport lines
— Enables a better use ratio (kW/kVA) for installations

Technical benefits

— Helping to control voltage throughout the transmission and distribution system
— Discharging power lines and power transformers
— Reducing level of system losses

When Compensate PF at MV?

Basically Medium Voltage(6.6/11/33kV) must be compensated when working with，

Industrial installation with medium voltage distribution networks,
As a general rule, installations that distribute and consume energy at MV are eligible to be compensated, such as smelting factory,pumping Plant, desalination plants, textile factories, cement factories, the petrochemical industry, steel mills, etc.
Also such as generation, distribution systems, and industrial installations with MV distribution and LV consumption.

Types of PF compensation at MV
