BST-TH — high-power electromechanical stabiliser 400–3000 kVA
Country: Italy · Model: BST-TH
The BST-TH covers the 400–3000 kVA range where toroidal variators are no longer enough, and regulates voltage with motorised column autotransformers. Such stabilisers are installed at a company's main supply, after a transformer substation or in front of a powerful production line.

Description
A column variator consists of several rods with windings along which the rollers of the current collector move, so one unit carries currents that a toroidal design cannot. The drive moves the rollers automatically, and the output voltage changes smoothly, without steps and without breaking the circuit. The cabinet is built on a self-supporting frame that carries the weight of the unit, so the stabiliser is transported without a pallet. At installation this shortens preparation, and the unit is placed directly on the foundation or on the cover of the switchroom cable duct. The installation place is planned with ventilation in mind, since the losses of column autotransformers are removed by the room air.
How to choose
For loads up to 300 kVA the BST-T on toroidal variators is enough. The BST-TH is chosen when the design power, allowing for growth, exceeds 400 kVA, and the upper limit of the range is 3000 kVA. The input voltage range and number of phases are agreed with the manufacturer based on measurements of the grid at the site.

FAQ
What is the power of BST-TH stabilisers?
The range covers 400–3000 kVA. Smaller loads of 10–300 kVA are covered by the BST-T series.
Why does the BST-TH use a column rather than a toroidal variator?
The column design is made up of several rods with roller current collectors and carries much larger currents than a toroid. That is why it is used at powers from 400 kVA.
How is a high-power BST-TH stabiliser transported?
The unit is built on a self-supporting frame and transported without a pallet, which simplifies loading and installation in the switchroom.
Does the BST-TH distort the grid voltage waveform?
No, regulation is by autotransformer, the voltage changes smoothly, without semiconductor switches or steps, so the waveform does not deteriorate.
Where are BST-TH stabilisers installed?
At a company's main supply, after a transformer substation or in front of a powerful production line with a load of 400–3000 kVA.
