The Kyoritsu 4118A Loop/PFC/PSC Tester is a versatile instrument designed for professionals involved in electrical installations and safety assessments. With its advanced features and multiple testing capabilities, this tester ensures comprehensive analysis of loop impedance, prospective fault current (PFC), and prospective short circuit current (PSC) in electrical systems.

• Ideal for testing and verifying the integrity and safety of electrical installations in residential, commercial, and industrial settings.

• Valuable for ensuring compliance with safety standards and regulations by assessing loop impedance, PFC, and PSC in electrical circuits.

• Useful for analyzing the potential fault currents in circuits and sizing protective devices to enhance electrical system safety.

• Beneficial for routine maintenance and troubleshooting tasks to identify and address issues related to loop impedance and prospective fault currents.

Loop Impedance Testing:

• The primary function of the Kyoritsu 4118A is to measure loop impedance, providing valuable information about the impedance in the electrical circuit. This is essential for assessing the effectiveness of the electrical installation and ensuring compliance with safety standards.

Prospective Fault Current (PFC) Measurement:

• The tester measures prospective fault current (PFC), indicating the maximum current that could flow in a circuit under fault conditions. This information is crucial for determining the adequacy of protective devices and ensuring safety in the event of a fault.

Prospective Short Circuit Current (PSC) Measurement:

• PSC measurement helps determine the maximum current that could flow in a circuit in the event of a short circuit. This data is vital for sizing protective devices and ensuring the electrical system can handle fault currents without compromising safety.

Digital Display:

• Equipped with a digital display, the tester provides clear and precise readings of loop impedance, PFC, and PSC values. The digital format enhances visibility and facilitates quick assessments of the electrical system's safety and performance.

Selectable Test Voltages:

• The tester may offer selectable test voltages, allowing users to choose the appropriate voltage for the specific testing requirements. This flexibility ensures accurate measurements in different electrical environments.

Auto-Ranging:

• The auto-ranging feature enables the tester to automatically select the appropriate measurement range based on the impedance or current being measured. This simplifies the testing process and ensures accurate results.
