We're in charge of development and quality control for instruments that measure electric power and the energy. With the recent enactment of energy conservation laws and ISO14001, energy-savings has become an important topic in many fields.

The power measurement unit that we're developing, EcoMonitor, monitors the volume of electric power and the energy usage at factories, and determines whether any of that electricity is being wasted. Also, acquired data from multiple locations can be aggregated, observed, and analyzied over a network. We are responsible for maintaining the development and manufacturing quality of these measuring instruments, as well as the market quality which means the degree to which the product can satisfy the customers' requirements.

PZ4000 monitors measuring results of the Power Measurement Unit.

Previously we were using a power meter that could only display electric data numericaly. But since many new kinds of electric equipments were coming out, and during our work we were seeing more and more waveforms that were extremely distorted. So, we realized we needed a measuring instrument with wide frequency bandwidth that could simultaneously measure power and waveforms. Therefore we decided to bring in thePZ4000 Power View.

We normally measure voltage, current, and power, but harmonics are also generated from the power supply system, so we can view the waveform directly with thePZ4000 and evaluate the system while confirming whether waveforms occurr as predicted. This power analyzer (measuring instrument) allows us to make waveform observations never before possible, and has improved our working efficiency tremendously. Until now we required several oscilloscopes and power meters, but the PZ4000 can measure 3 phase power system and display the waveform and measured values on the screen in real time, which is incredibly convenient. The screen is a color LCD that is very easy to see, and one unit takes up a relatively small space which helps us out.
