NIHON TECHNO CO., LTD.

Electricity safety management

  • Protect electricity

    • Security improvement
    • Electrical safety management

    The ES SYSTEM, independently developed by the Company, conducts constant 24/7 monitoring of power outages, instantaneous voltage drops and ground leakages, etc. When the ES SYSTEM detects abnormalities, it automatically reports this to the Company’s monitoring center. The monitoring center quickly grasps the location of electricity accidents and calls for an emergency response from the person in charge on site. In addition, the Company’s nationally qualified electrical management engineers and electrical management engineers belonging to the NIHON TECHNO Cooperative Association/Nichidenkyo provide safety inspections and their own warranty services as stipulated by the Electricity Business Act.

    Electrical safety management

      Urgently go to the site and restore equipment

  • ES SYSTEM surveillance function

    The Company’s “ES SYSTEM” is the main device installed in high-voltage electrical equipment (cubicle systems), which monitors the operating status of cubicle systems 24/7. In addition, the ES SYSTEM is aligned to the electronic electricity meters provided by electric power companies and is equipped with functions to measure the maximum electricity demand value and electricity usage for 30-minute periods that is used to determine electricity fees.

    • Complete power interruption surveillance

      Complete power interruption surveillance function detects power outages of high-voltage electrical equipment (cubicle systems, etc.) and automatically reports this to the Company’s monitoring center. While notifying the customer’s designated contact, the electrical management engineer responsible for the equipment promptly responds. A single power outage can spread to 500 to 1,000 incidents in the same area. To minimize the damage to the customer or nearby facilities, surveillance is conducted 24/7, 365 days a year.

    • Instantaneous voltage drop surveillance

      Instantaneous voltage drop is the phenomenon of a sudden drop in voltage (about 0.07 to 0.2 seconds). Precision machinery and information systems are affected when voltage drops and may suffer enormous damage. The instantaneous voltage drop surveillance function operates when there is a sustained drop in the input voltage to 80V for 0.03 seconds. Obstructions to operations are mitigated by stopping equipment due to prompt notification to customers.

    • Ground leakage surveillance

      Ground leakage is the phenomenon of electricity leaking elsewhere due to poor insulation of electrical wire and electrical equipment. If left alone this can lead to serious accidents including those involving electric fires and electric shocks. The ground leakage surveillance function constantly monitors the insulation status of cubicle systems, and automatically reports to the monitoring center as well as the engineer in charge if the set value is exceeded. It correctly detects ground leakage that cannot be confirmed with the human eye.

    • Transformer temperature surveillance

      A transformer may experience temperature abnormalities due to factors including excessive use of electricity and deterioration in transformer oil (or insulating oil). Frequent abnormalities lead to damage and accidents with the entire cubicle systems. The transformer temperature surveillance function monitors the transformer temperature based on past data, and automatically reports to the monitoring center and the engineer in charge if there is abnormality. Damage and accidents with the cubicle systems are prevented, with an understanding of the target period for changing the transformer.
