6%, 13% series reactor protection device for preventing harmonic intrusion phenomena
Harmonic Ingress Phenomenon Prevention Device It is suitable for cases where overcurrent and overheating relays operate in a 6.6kV system leading capacitor circuit. Instead of attenuating or eliminating the harmonics themselves like a filter, it prevents the amplification phenomenon caused by harmonics. Manufactured by Otowa Electric Industry, a specialized manufacturer of lightning protection products, including surge protectors (Arresters, SPD, LA, Surge Protectors), lightning countermeasure products, and induced lightning countermeasures.

basic information
*Features* 1. Suitable for operation in a 6.6kV system phase advance capacitor circuit when there is an occurrence of overcurrent or overheating relay. 2. Connected between the terminals of a 6% or 13% series reactor, it is normally in an open state, so it does not respond to harmonics within the guideline. (There is no hindrance in conducting dielectric strength tests in normal power distribution equipment.) 3. Instead of attenuating or eliminating the harmonics themselves like a filter, it prevents the amplification phenomenon caused by harmonics. It responds to transient overcurrents and quickly restores to a normal state. 4. It addresses the phenomenon of harmonic influx associated with overcurrent and noise (hum) originating from the 5th harmonic, but does not address noise (hum) without overcurrent that primarily arises from the 3rd harmonic. 5. It also operates and has an effect of attenuation on switching surge overcurrents generated by the opening and closing of LBS. 6. Compact and lightweight, it can be easily installed without the need for extensive construction.

Company information
OTOWA is the only manufacturer in Japan specializing in lightning protection, having explored "lightning" since its establishment. We want to create a safe and secure society that does not fear the natural threat of "lightning." We will realize this wish with our advanced lightning protection systems. ◆ A Wide Range of Products Available We offer a variety of products, including surge protectors for power distribution, as well as those for offices, factories, railway vehicles, and general households. We also accommodate custom orders, so please feel free to consult with us. ◆ Consulting for Lightning Protection Lightning protection varies depending on various conditions such as location. OTOWA will propose the most suitable lightning protection measures for those conditions. ◆ World-Class Lightning Testing Facilities Using top-class testing facilities and a diverse range of testing equipment, we conduct product evaluation tests and development in-house. Our achievements are highly regarded, and we also accept contract testing (Lightning Technology Center). ◆ Unique Quality of Zinc Oxide Devices We produce zinc oxide (ZnO) devices under strict management. These devices are the heart of surge protective devices (SPDs) and are indispensable for lightning protection.
