CASE STUDY

[Japan] At a renewal of cubicle-type high-voltage substation, it was difficult to select an appropriate transformer capacity because the current load capacity was unknown.

[Iran] I work as technical safety and electrical inspection consultants, inspecting electrical installations in residential, commercial, healthcare, and industrial facilities. With my previous instrument, each time I performed an RCD test, I had to repeatedly select, configure, and run each test item manually, which made inspections time-consuming. In addition, the instrument did not feature Anti-Trip technology. As a result, RCDs would often trip unnecessarily during loop impedance testing, causing interruptions and further reducing inspection efficiency.

[Saudi Arabia] The previous methods used were complex, and there were also issues with measurement accuracy, as they required a combination of measurements and supplementary calculations to obtain results.

[Spain] When performing fault diagnosis on electrical installations during the construction and repair of residential and commercial facilities, we used instruments such as multimeters, voltage testers, and clamp meters. However, we often could not perform sufficiently thorough diagnostics and had to rely on trial and error, experience, and intuition. Particularly in areas with a large number of aging residential and commercial facilities, it was necessary to respond to numerous electrical problems throughout the year. Accurately and efficiently identifying the cause of a fault was a significant challenge. In addition, when the cause could not be identified, it was often necessary to replace part or all of the equipment, resulting in additional time and cost burdens for customers.

I had to carry bulky clamp meters and separate instruments for AC and DC measurements.

[Japan] We had been using an older clamp meter, which made it difficult to take measurements in areas with densely packed wiring, making circuit checks more time-consuming. Since it did not include multimeter functions, we also had to carry a separate card-type tester, which required the additional hassle of winding and managing test leads.
