CASE STUDY

[India] Over the past 15 years, we have been operating as an engineering consultant specializing in services such as safety audits and electrical failure analysis. Our work includes the regular inspection and evaluation of electrical systems across a wide range of facilities. As part of these routine audit activities, accurate measurement of loop impedance is essential. However, since many of the systems are protected by Residual Current Devices (RCDs), conventional testing methods can cause unintended tripping, leading to operational disruption. Therefore, we require a reliable solution or instrument capable of measuring loop impedance without tripping the RCD. This capability is critical to ensure efficient, non-intrusive testing on systems that are in operation and to maintain continuity in the audit process.

[Japan] Cables are crowded in the distribution board and power distribution board and we couldn't clamp the target cables. There's no space to put the clamp jaws into the crowded area.

【Japan】 * Working place is usually dark since the circuit breaker is turned off at insulation resistance measurement. * Difficult to see the display in the dimly lit location. * Not often, but sometimes the worker forget to turn off the circuit breaker. * Misunderstanding easily happens if multiple scales should be checked depending on the output voltage.

【Indonesia】 Multiple testers are required to check the power of a busbar (80x10 mm) or in cable crowded area. I've been worried about touching with a busbar adjacent to the cable I wish to clamp.

【Japan】 Since I need to bring a lot of tools for electrical work, I always bring the minimum required tools. On the rare occasion, I want to measure and check the current but I only have a traditional tester and cannot measure current on site.
