TBQ combines autotransformer voltage regulation with parallel capacitor compensation during starting. It controls starting current and supply-line voltage drop for large 6 kV and 10 kV motors.
Typical Applications
Motors:Large 6 kV and 10 kV motors.
Uses: Reduced-voltage starting with reactive-power compensation.
Combines autotransformer voltage control with parallel compensation capacitors.
Integrated Compensation
Starting current is adjustable from 1.3 to 2.8 times rated current.
Adjustable Starting Current
Starting voltage can be set to suit load characteristics.
Adjustable Initial Voltage
Transfers to normal operation as motor voltage approaches full voltage.
Full-voltage Transfer
Supports constant-current and constant-time starting, with optional soft stopping.
Starting Control Modes
A multilingual touch screen displays parameters; remote communication interfaces are optional.

●The capacity of the compensation device is typically approximately 40% of the motor capacity, determined through specific calculations based on the power grid, motor, and load, and it comprises multiple compensation cabinets.
● The capacity of a single compensation cabinet is 1000–3000 kvar, with dimensions of (1100 × 1600 × 2650) mm (width × depth × height).
