1)Filter Resistor

The resistor will apply in HVDC or SVC system, to eliminate the high frequency harmonic, so as to improve the power quality supplied to the customer.

2)Starting Resistor

The charging resistor applied in HVDC, SVG, STATCOM, UPFC system to limit the current at the system initialization stage. When launching the systems, the initial current is times of the normal level, which may lead to severe problem to the system. Therefore, a charting resistor is employed to limit such current. The resistor must withstand pretty large current and the over voltage.

3） Neutral Earthing Resistor

The product is connected between the neutral point of power system and the earth. When the system has ground fault, the resistor will limit the fault current, and cut off the fault line via the converted current signal or give a fault alarm signal. At the same time the system is connected with the resistor to prevent the insulators of the line and equipment from damage to reduce economic losses.
