Product Introduction

In power systems, portable short-circuit grounding sets and personal protective grounding lines play a crucial role in preventing accidental energization of electrical equipment and power lines, as well as in eliminating induced voltages and discharging residual charges. To prevent substandard grounding equipment from entering the power system, our company has developed the "Grounding Set Tester." This instrument was designed in strict accordance with the *Technical Standards for Portable Short-Circuit Grounding Sets* and the *Preventive Testing Regulations for Power Safety Tools and Equipment*—the latest standards issued and implemented by the State Power Corporation. It serves to facilitate the necessary preventive testing of these products within power systems.

Technical Parameters

Product Features

◆ The HC-50B Grounding Wire DC Resistance Tester is controlled by a high-speed single-chip microcontroller, featuring a high degree of automation and user-friendly operation.

◆ The HC-50B employs advanced power supply technology, delivering stable output current, high output voltage, rapid measurement speeds, and a wide measurement range.

◆ The HC-50B features a built-in real-time clock and perpetual calendar, capable of storing up to 1,000 sets of test data for convenient retrieval by the user at any time.

◆ It incorporates comprehensive protection functions; the internal power supply automatically shuts down in the event of overheating, effectively preventing damage to the unit. Additionally, it includes a voltage lead reverse-connection warning feature to prevent data inaccuracies caused by incorrect test lead connections.

◆ Equipped with a 7-inch, high-brightness color LCD touchscreen display that remains clearly legible even under strong lighting conditions; the device supports full touchscreen operation with seamless switching between Chinese and English interfaces.

◆ The instrument features a built-in thermal printer, allowing for the real-time printing of test data.

◆ Utilizing intelligent power management technology, the instrument consistently operates in a low-power mode, effectively minimizing internal heat generation and conserving energy.
