Shunt Reactors in Saudi Arabia

A shunt reactor is a piece of electrical equipment used in high voltage power transmission systems to stabilize the voltage during load variations. A traditional shunt reactor has a fixed rating and is either connected to the transmission line all the time or switched in and out depending on the load.

A three phase shunt reactor is generally connected to 400KV or above electrical bus system for capacitive reactive power compensation of the power system and to control dynamic over voltage occurring in the system due to load rejection.

The shunt reactor should be capable of withstanding maximum continuous operating voltage (5% higher the rated voltage in case of 400 KV system) under normal power frequency variation without exceeding the top spot temperature of 150oC at any part of the shunt reactor.

The shunt reactor should be of gapped core type or magnetically shielded air core type. Both of these designs help to maintain the impedance of the reactor fixed. The impedance should be maintained at a constant value for avoiding harmonic current generated due to the system over voltage.
shunt reactor
The shunt reactor has mainly core losses during its normal operating condition. So, care should be taken for minimizing the core losses during design.

Measurement of Losses in Shunt Reactor
We should measure the losses of a shunt reactor at rated voltage and frequency. But for very high voltage shunt reactor, it may be difficult to arrange such a high test voltage during measurement of losses. This difficulty can be overcome, by measuring the losses of the shunt reactor at any voltage lower than the system voltage of the reactor. Then this measured loss is multiplied by the square of the ratio of rated current to the current of the reactor at applied reduced test voltage to obtain the loss at rated voltage.

About Saudi Arabia

Arabic is the official language of Saudi Arabia and the primary language used in all dealings and public transactions. English serves as an informal second language in the Kingdom and is spoken by a large section of its society. All road signs are bilingual, showing information in both Arabic and English. 

Saudi Arabia’s rich heritage and traditions have been shaped by its position as a historic trade hub and the birthplace of Islam. In recent years, the Kingdom has undergone a significant cultural transformation, evolving centuy-old customs to fit the contemporary world we live in today.

Spring in Saudi Arabia can be brisk, particularly in the north, where the temperature at night can drop below 15 degrees C. The central and southern regions are warmer, averaging around 20 degrees after nightfall. Rainfall is at its highest during spring, particularly in the central region and in the southwest over the Asir Mountains.

Al-Saih is one of the main and active cities in the present and future of the Kingdom of Saudi Arabia, which is the modern capital of Alkharj and its administrative and economic center with a population of more than 376 thousand people. … Alkharj has been crowned as the capital of dairy industry.
