Typically, when conducting an AC dielectric strength test, voltage is applied between the windings of the equipment and between the windings and the enclosure (earth potential) to verify insulation strength. In this case, the load from the perspective of the testing device is capacitive (equivalent to a capacitor). When realizing a testing device that corresponds to such a load, this "self-compensating AC dielectric strength testing device" has been designed to be as lightweight and compact as possible, focusing on its capacitive nature. Similarly, the compensation reactor type AC dielectric strength testing device has been widely adopted for the same purpose. Additionally, in small-capacity dielectric strength testing devices (standard type), it is common for the load to be unrelated to capacitive loads.

The "Amorphous Scott Connection Transformer" is used to convert three-phase AC power into single-phase AC power while minimizing the no-load loss (standby loss) of the Scott connection transformer, contributing to energy savings and CO2 reduction, particularly demonstrating its effectiveness in emergency power supplies. Conventional Scott connection transformers were made with silicon steel cores, but Jibu Electric has utilized amorphous alloy for the core, reducing no-load losses to about 1/4 to 1/6. The importance of emergency power supplies (generators) has significantly increased in factories, office buildings, and hospitals in case of emergencies. To simultaneously extract single-phase and three-phase power, a Scott connection transformer is necessary, and the Amorphous Scott Connection Transformer reduces no-load loss (standby loss) to 1/4 to 1/6. This allows for reduced generation costs when emergency power is needed, and when converted to electricity charges, it can be reduced to about half compared to conventional products.

Molded transformers do not use insulating oil, making them excellent in fire resistance and fire prevention. They are used in facilities that prioritize disaster prevention, such as electrical rooms in office buildings, hospitals, schools, and other public facilities, as well as in distribution boards in factories. Jibu Electric offers customized amorphous molded transformers that utilize amorphous alloys with lower losses and high energy-saving effects compared to conventional products. The JAM series is a high-efficiency, energy-saving type of transformer that significantly exceeds the top runner standard values set from the fiscal year 2014. Amorphous molded transformers can reduce standby power (no-load loss) to about one-third compared to conventional silicon steel plate types, making them environmentally friendly and cost-effective transformers. They are also optimal as grid-connected transformers for equipment with relatively low equivalent load rates, such as renewable energy generation, which has seen increased demand in recent years, including solar power generation.

Jibu Electric Co., Ltd., a specialized manufacturer of special transformers, has developed a series of H-type dry amorphous transformers (JAH series) in response to customer demands, focusing on environmental friendliness and economic efficiency. We offer custom-made H-type amorphous transformers for industrial equipment that require small-batch production according to customer specifications. Amorphous transformers reduce no-load losses to about 1/3 to 1/6 compared to conventional products, achieving the highest energy efficiency in transformers. Leveraging these features, they are also ideal for renewable energy fields, power conditioners, UPS systems, and more. Amorphous transformers focus on reducing no-load losses. Since transformers are long-lasting products, minimizing no-load losses can lead to significant energy-saving effects. No-load loss (iron loss) refers to energy losses that occur even when electricity is not being used. Reducing this loss enhances power consumption efficiency and contributes to global environmental conservation. For more details, please contact us or refer to our catalog.

Amorphous insulation transformers are ultra-low loss insulation transformers installed on the AC output side of the power conditioner during the grid connection of solar power generation systems. By adopting amorphous transformers for solar power generation insulation transformers, the amount of carbon dioxide emissions is reduced by approximately 800 kg per year (equivalent to about 60 cedar trees) compared to conventional silicon steel plate transformers. Additionally, due to this energy-saving effect, an increase in profits of about 50,000 yen per year (approximately 1 million yen over 20 years) is expected (based on an example of a 3-phase 50 kVA transformer from Jibu Electric with an average load factor of 20% for solar power generation). It demonstrates significant energy-saving effects in areas with relatively low equivalent load factors, such as solar power generation. For more details, please contact us or refer to the catalog.

Molded transformers are supplied by electric utility companies, including renewable energy generation operators. They are incorporated into system interconnection receiving panels and electrical rooms or distribution boards in buildings, hospitals, and schools to convert electricity to the optimal voltage. Due to recent energy-saving measures and increased awareness of environmental issues, there is a demand for products with excellent energy-saving performance. Our company will launch the "Amorphous Molded Transformer," which employs amorphous alloy in the core of the molded transformer, achieving reduced losses and high efficiency from low load to rated load compared to conventional products.

When using amorphous alloy strips for iron cores, compared to magnetic materials such as silicon steel sheets with crystalline structures, the rotation of atoms becomes easier when the magnetic flux changes, resulting in reduced hysteresis loss (loss during magnetic flux passage). Additionally, due to the thinner plate thickness, eddy current losses are also minimized. Therefore, amorphous iron cores reduce iron loss compared to conventional silicon steel plate iron cores. Transformer losses can be broadly categorized into two types: "no-load loss," which occurs regardless of the load, and "load loss," which varies with the load current. No-load loss primarily refers to iron loss occurring in the iron core. Load loss, known as copper loss, is due to the resistance of the transformer windings caused by load current. Amorphous transformers focus on minimizing no-load loss among these losses. Since transformers are long-lasting products, reducing no-load loss can lead to significant energy-saving effects.

- Like conventional lighting and power shared transformers, three-phase and single-phase can be drawn simultaneously. - By separating the circuits of the three-phase side and the single-phase side, there is less electrical interference between them compared to lighting and power shared transformers, allowing for higher quality electricity to be obtained. - Any grounding method can be applied to both the three-phase side and the single-phase side. - The name "Lighting and Power Separation Shared" is a unique designation created by Jibu Electric.
