MHPA Unit 3 turbine down due to an electrical fault

Jun 18, 2020

The turbine 3 of the 720 MW Mangdechhu Hydro Power plant (MHPA) in Trongsa has been un-operational for almost three weeks. A turbine is an electricity-generating machine of a hydropower plant.

On May 31, a fault was detected in the rotor of the turbine while mandatory checking was carried out in all the electrical components of the machine.

Chief Electro-Mechanical of MHPA, Kaushik Maulik, said that a generating machine has lots of components that have to work independently and flawlessly. “This fault is a rare fault. It does not occur on regular basis. But unfortunately our Unit 3 developed the fault and we are restoring it.”

The projects officials said that they have identified the sudden electrical fault developed in the turbine and the machine will be operational by this weekend.

The Managing Director of MHPA, A.K.Mishra said that this however has not affected energy generation. “There is no loss in the energy generation because the water is currently available only for three machines.”

Meanwhile, even with unit 3 down, the three others turbines generated 600 MW as of yesterday. MHPA has four turbines, each with a generating capacity of 180 MW.
