7. OVR WT 3L 690 P TS
Keep the wind turbine running
Due to their height (over 100 meters) and location, wind turbine are often exposed to direct & indirect lightning strike consequences i.e: transient surges, overvoltages and over currents. These induced consequences will directly affect power and signal leads and damage costly equipment.
Actual variable-speed wind turbines are equipped with PWM (Pulse Width Modulation) controlled inverters using IGBT or IGCT in order to regulate their output voltage and frequency. These technologies, if not filtered properly, generate peak transient overvoltages surperimposed on the PWM control voltage. It is therefore necessary to use SPDs with a specific withstand to these PWM, the repetitive peak voltage withstand characteristics (Urp), on the lines between the converter and the generator either in Doubly-Fed or Full-Converter electrical drive train. That’s why ABB provides OVR WT Surge Protective Device to keep the system running and reduces downtime events by protecting close to the rotor bearing and to the converter.

Surge protector, also called lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When an electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct shunts in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit.
Surge protector, suitable for AC 50 / 60HZ, rated voltage 220V / 380V power supply system, to protect indirect lightning and direct lightning impact or other transient overvoltage surges, suitable for homes, tertiary industry and industry Requirements for field surge protection.

ABB Surge Protective Device Model

Basic Features:
1.Protection of large flow, extremely low residual voltage, fast response time; 2.Using the latest arc extinguishing technology to completely avoid fire; 3.Using temperature control protection circuit, built-in thermal protection; 4.With power status indicator Surge protector working status; 5. Rigorous structure, stable and reliable work.

Working principle:
Surge protection device (Surge protection Device) is an indispensable device for the lightning protection of electronic equipment. In the past, it was often referred to as "lightning arrester" or "overvoltage protector". The English abbreviation is SPD. The transient overvoltage into the power line and signal transmission line is limited to the voltage range that the equipment or system can withstand, or a strong lightning current is discharged into the ground to protect the protected equipment or system from damage from impact.
The type and structure of the SPD are different for different purposes, but it should include at least one non-linear voltage limiting element. The basic components used in surge protectors are: discharge gap, gas-filled discharge tube, varistor, suppression diode and choke coil.
