HVCZ3510 Ground Wire Group Resistance Tester Overview


 

In the power system, portable short-circuit grounding wires and personal protective grounding wires play a crucial role in preventing electric equipment and lines from sudden energization, eliminating induced voltage, and discharging residual charge. To prevent unqualified grounding wires from entering the power system, our company has developed the "Ground Wire Group Resistance Tester" based on the "Technical Standard for Portable Short-Circuit Grounding Wires" and the "Preventive Test Regulations for Electric Power Safety Tools and Devices" newly issued and implemented by the State Power Corporation, providing services for the power system to complete necessary product preventive tests.


 

HVCZ3510 Ground Wire Group Resistance Tester Functional Features


 

The whole machine is controlled by a high-speed microcontroller, featuring high automation and simple operation.


 

The instrument adopts brand-new power supply technology, with stable output current, high output voltage, fast measurement speed, and wide range, suitable for testing various portable short-circuit grounding wires and personal protective grounding wires.


 

The instrument comes with a built-in clock and perpetual calendar, and can store 20 sets of test data for convenient query at any time.


 

The protection functions are comprehensive, with automatic protection after internal power supply overheating, effectively preventing damage to the power supply. It also features a voltage line reverse connection warning to prevent inaccurate test data due to incorrect connection of test leads.


 

The instrument uses a 128X64 dot-matrix LCD screen, with all operations displayed in Chinese for user convenience.


 

The instrument comes with a built-in thermal printer that can print test data in real time.


 

Intelligent power management technology ensures the instrument always operates at minimum power, effectively reducing internal heat generation and saving energy.
