CASE STUDY

[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.

[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.

[Cyprus] Previously, measurement results had to be recorded manually, making data management and report generation time-consuming. In addition, I didn’t have a single instrument that could perform continuity, insulation resistance, earth resistance, and RCD tests.

[Japan] There was an installation job for an EV/PHEV charger, but although it was installed, we were unable to verify whether the charger was functioning properly, so we had to confirm proper operation using the customer’s PHEV.

[Japan] For electrical installation inspections, we had to carry both a simplified earth resistance tester and a low-voltage insulation resistance tester, leaving both hands occupied.

【Singapore】 When measuring loop impedance of EVSE by using multifunction tester and EVSE adapter, built-in RDC-DD (6 mA) trips sometimes. So I need to bypass the RDC-DD, that is extra time-consuming work.
