Instantaneous Voltage Drop Compensation Device TSP: Why is protection necessary?

Instantaneous Voltage Drop Compensation Device TSP: Why is protection necessary?

"TSP" protects the line from product defects caused by instantaneous voltage drops and damages from equipment failures.

Variable speed motors, computers, electromagnetic switches, high-pressure discharge lamps, and motors with magnetic switches may be affected by instantaneous voltage drops, potentially causing operational issues. Silicon manufacturers may be impacted during processes such as polishing, etching, and cleaning, while device manufacturers may experience effects during CVD, sputtering, photolithography, etching, ion implantation, diffusion, and cleaning processes. Therefore, the "SEMI-F47" standard requires semiconductor manufacturing equipment to have resistance to instantaneous voltage drops of 50% for a duration of 0.2 seconds or less, or 30% for a duration of 0.5 seconds or less. [Examples of damage due to instantaneous voltage drops] ■ Product defects → Batch processing equipment (lot out) ■ Equipment failure → Failure of expensive components, etc. *For more details, please feel free to contact us.

Instantaneous Voltage Sag Compensation Device TSP: What is an instantaneous voltage sag?

Instantaneous Voltage Sag Compensation Device TSP: What is an instantaneous voltage sag?

"TSP" protects the line from product defects caused by instantaneous voltage drops and damages from equipment failures.

Instantaneous voltage sag refers to a condition where the voltage drops instantaneously (for 0.07 to 2 seconds) due to lightning strikes or transmission accidents affecting the power lines. Lightning-induced events are natural phenomena and cannot be eliminated. The "TSP" backs up the power supply voltage with high-speed switching of 0.002 seconds during the occurrence of instantaneous voltage sag. During an instantaneous voltage sag, the SAG-VIEWER function allows for the recording of events such as the occurrence date and time, voltage sag level, duration of voltage sag, and voltage waveform. 【Duration of instantaneous voltage sag by voltage level in the transmission system】 ■500kV → 0.07 to 0.3 seconds ■275kV → 0.07 to 0.3 seconds ■164kV → 0.1 to 2 seconds ■77kV → 0.1 to 2 seconds ■6kV → 0.3 to 2 seconds *For more details, please feel free to contact us.

Instantaneous Voltage Drop Compensation Device TSP - What is TSP?

Instantaneous Voltage Drop Compensation Device TSP - What is TSP?

"TSP" protects the line from product defects caused by instantaneous voltage drops and damages from equipment failures.

Typically, when supplying commercial power to the load side via SCR, energy is charged into the electric double-layer capacitor (EDLC). However, in the event of an instantaneous voltage drop, the detection circuit switches within 2 milliseconds, supplying the energy charged in the electric double-layer capacitor (EDLC) as AC output converted by the inverter to the load side. *For more details, please feel free to contact us.*

Instantaneous Voltage Drop Compensation Device TSP: Annual Occurrence of Instantaneous Voltage Drops

Instantaneous Voltage Drop Compensation Device TSP: Annual Occurrence of Instantaneous Voltage Drops

"TSP" protects the line from product defects caused by instantaneous voltage drops and damages from equipment failures.

In a factory located in the Hokuriku region, there were a total of 20 occurrences of instantaneous voltage drops over the course of a year, all with a voltage drop rate of 20% or more, with the duration of these drops ranging from 41.6 milliseconds to 115.23 milliseconds. It has been reported that each consumer experiences an average of 5 instantaneous voltage drops per year, with a voltage drop of 20% or more. In areas with frequent lightning strikes, there can be more than 10 to 20 occurrences per year. The duration of instantaneous voltage drops is mostly around 0.1 seconds, and theoretically, it does not exceed 2 seconds, which is the switching time of the power company. *For more details, please feel free to contact us.*

What is the difference between UPS and TSP in terms of instantaneous voltage drop compensation devices?

What is the difference between UPS and TSP in terms of instantaneous voltage drop compensation devices?

"TSP" protects the line from product defects caused by instantaneous voltage drops and damages from equipment failures.

A "UPS" (Uninterruptible Power Supply) is a device that charges commercial power into a battery and converts that energy into alternating current (AC) using an inverter to supply it to the load side. In the event of a momentary voltage drop, even if the commercial power source disappears, the energy charged in the battery can typically supply AC output to the load side for about 15 to 30 minutes. 【Differences between UPS and TSP】 ■ The difference between charging power into a battery or charging it into an electric double-layer capacitor (EDLC) ■ The difference between constant inverter output and constant commercial output ■ The difference in lifespan between batteries and electric double-layer capacitors ■ The difference in protection time *For more details, please feel free to contact us.

Instantaneous Voltage Drop Compensation Device TSP: Why TSP?

Instantaneous Voltage Drop Compensation Device TSP: Why TSP?

"TSP" protects the line from product defects caused by instantaneous voltage drops and damages from equipment failures.

"UPS" and "TSP" are not competing products; they are fundamentally differentiated by "what is being protected" and "the required protection time." In cases of large-capacity protection, TSP offers significantly better cost-effectiveness, which is why the electric double-layer capacitor type TPS has been selected in recent years. [Selection Examples] ■ Required Protection Time (in minutes) Protection time during instantaneous voltage drops needs to be 15 to 30 minutes due to fail-safe considerations. → Select UPS ■ Protection against pure instantaneous voltage drops (protection time under 2 seconds) → Select TSP Single-phase products over 5kVA or three-phase products are superior in initial/running costs and lifespan. → Select UPS For single-phase products under 3kVA, they are available at a lower cost. *For more details, please feel free to contact us.
