Produ c t s Q&A about GDT Q1 Our Strength What is Follow Current? A1 Follow current is a phenomenon in which, after a GDT discharges due to a surge, the discharge continues even though it should normally stop. Instead, current supplied from the power source or the circuit continues to flow through the GDT. When follow current occurs, it can cause abnormal heating, which may lead to component damage or burning. In Quality addition, the circuit may remain short-circuited, resulting in issues such as fuse blowout. For these reasons, GDTs cannot be used alone on power lines or in environments where large amounts of current are available. ISO 9001 AQL Sampling Q2 Can Follow Current Be Prevented?

Single Sampling Plan for General Inspection - Level-I and the A2 Follow current can be prevented by connecting a varistor or resistor in series with the GDT.

Warranty A3 In general, we recommend replacing GDTs after 10 years of installation. However, the actual service life may vary depending on the magnitude and frequency of lightning surges and the operating environment. Therefore, Sankosha warrants its products for a period of one year periodic inspection of insulation resistance or DC sparkover voltage is recommended.

However, plastic bags may be substituted for plastic trays without prior notice. A6 Deterioration can be suspected if measurements taken with an arrester tester (PD-2N) show that the DC spark- over voltage or insulation resistance is outside the specified range. In addition, if there are obvious external abnor- malities such as burn marks from surge events, the GDT may be deteriorated and replacement is recommended. Q7 What Is a Fail-safe Mechanism? Variety of line-ups Sankosha's GDTs support the safety of communications, power, and electronic equipment worldwide, thanks to A7 A fail-safe mechanism is a protective structure designed to ensure that equipment is kept in a safe condition even if the GDT enters an abnormal state. Under normal conditions, a GDT remains insulating and discharges only when a their high surge resistance, low static electricity, and highly reliable operation. Based on many years of experi- surge occurs. However, in rare cases, excessive surges or overloads can cause the internal structure to short-circuit. ence, we have a wide product lineup that meets a variety of specifications and customer requirements, providing The fail-safe mechanism is designed to intentionally provide a controlled bypass path for current in such abnormal optimal solutions for a variety of markets and environments. situations, thereby preventing further equipment damage or fire risk. (This feature is implemented in our 3H/3J series GDTs.) Q8 What Is the Guideline for Selecting the DC Sparkover Voltage of a GDT? Customization Options A8 A GDT should be selected with sufficient voltage margin so that it does not affect the circuit during normal opera- tion. In general, the following guidelines are used: We offer customization options to meet your specific requirements. 1. Select a DC sparkover voltage approximately 1.5 to 2 times higher than the circuit’s maximum operating voltage. Fail-Safe Device This ensures an adequate margin to prevent false operation (unwanted discharge) during normal voltage conditions. A fail-safe (backup short-circuit mechanism) can be added 2. For signal lines such as communication circuits, select a voltage sufficiently higher to your selected GDT model. than the signal voltage. The sparkover voltage should be chosen to avoid interfering with normal communication levels defined by Combined Products (IsoMOV) the relevant communication standard. We can develop customized products that combine GDTs Typical examples include: and MOVs. • For a DC operating voltage of 12 V → 75‒90 V class • For a DC operating voltage of 24 V → 90‒150 V class Lead Line • For telephone and communication lines → 230 V class These values are commonly used, but the optimal voltage depends on the circuit specifications and the overall The length and thickness of the lead lines can be adjusted. protection design.
