Hitachi Industrial Equipment Systems Demand Monitoring Device (Power Distribution Monitoring System)

Hitachi Industrial Equipment Systems Demand Monitoring Device (Power Distribution Monitoring System)

Demand monitoring device with two-stage alarm to prevent exceeding contracted power.

It captures the electric energy pulse signals from the reference meter (integrated electric power meter), calculates the 30-minute demand to monitor that it does not exceed the contracted power, and outputs alarm signals (two-stage alarms for caution power and limit power). - A dedicated CT is clamped to the reference meter to directly detect 50,000 pulses/kWh (no pulse detector is needed). - If using a pulse detector (converter) to extend the pulse distribution or wiring distance, it can also capture pulse output from the converter (voltage-free pulse or open collector) at 50,000 pulses/kWh. - It can be used as a standalone unit, but it supports H-NET communication, allowing data transmission to upper devices (DE-SWA) for display on the demand monitoring screen and for report management.

[Case Study] Electricity Prices Soar Due to New Power Company Bankruptcy! Energy-Saving Measures Through Demand Monitoring

[Case Study] Electricity Prices Soar Due to New Power Company Bankruptcy! Energy-Saving Measures Through Demand Monitoring

No monthly system usage fee required! The dedicated display will inform you of the current power usage status!

The customer needed to change their electricity provider due to the bankruptcy of a new power company. Calculating the costs, it would result in an annual increase of 8 million yen in electricity bills compared to before, prompting them to consider the introduction of a demand monitoring device to further promote energy conservation. However, they faced difficulties as the wiring work from the school's power receiving equipment to the office could not secure a wiring route, and undertaking the construction would incur significant costs. Therefore, we proposed the construction of a system using our "Demand Monitoring System" with 'LoRa wireless' communication capable of reaching 5 km. There are no monthly system usage fees, and it can be implemented with just the cost of the equipment. 【Case Overview】 ■ Issues - The new power company went bankrupt, necessitating a change of electricity provider. - Wiring work from the school's power receiving equipment to the office cannot secure a wiring route. - Undertaking construction would incur significant costs. ■ Request: To easily retrofit the power receiving equipment and use wireless communication for demand monitoring in the office. ■ Proposal: LoRa wireless *For more details, please refer to the PDF document or feel free to contact us.

Demand monitoring device "e-Monitor"

Demand monitoring device "e-Monitor"

With a minimal burden, we can help you save energy and reduce costs!

The "e-Monitor" is a demand monitoring device that solves energy management issues. It automatically reads electricity usage at the end of each month. After that, you only need to retrieve the data as needed. In addition to monthly readings, hourly and daily readings are also possible, so you can leave regular readings to the "e-Monitor." 【Features】 ■ "Display monitor included" for checking electricity usage on-site ■ Demand monitoring and control signal output ■ Automatic memory of electricity consumption ■ Easy installation *For more details, please feel free to contact us.

What is demand monitoring? What is demand?

What is demand monitoring? What is demand?

By reducing peak power, the contracted power decreases, leading to a reduction in basic fees! An explanation of "demand."

Demand literally means "need" or "requirement," but in recent energy-saving measures, demand refers to the maximum power usage of consumers who use electricity. Furthermore, when we generally talk about demand values, we refer to the "instantaneous value of power usage: kW," but the demand value used in transactions with power companies refers to the "average power usage over a 30-minute period (demand time limit): kW (average capacity of operational load)." The time intervals of 30 minutes are called demand time limits (1 demand time limit = 30 minutes), and the demand value displayed on the power company's transaction meter is twice the value of the power used over those 30 minutes. When entering into a demand contract with a power company, the moment when the highest power occurs throughout the year is set as the demand, and that value becomes the monthly basic charge. *For more details, please refer to the PDF materials or feel free to contact us.
