- RD3215E
RD3215E high voltage insulation resistance tester has excellent anti-interference performance and is suitable for insulation resistance detection of large high voltage equipment and substation transmission lines. The true color touch screen displays clearly and is easy to operate.
Description
RD3215E high-voltage insulation resistance tester has complete insulation resistance parameter test functions and excellent anti-interference ability. It can be used for insulation resistance test of large-capacity high-voltage electrical equipment and transmission lines in substations under strong inductive electrical environment.
The instrument adopts a true color touch screen, and all test data and battery power are displayed on the same screen, which is clear and intuitive. The combination of knob switch and button makes the operation very simple. The instrument is suitable for testing the insulation resistance of large equipment such as electrical equipment, transmission lines, etc. under large capacity, high voltage, and strong inductive electrical environment.
Features
The instrument adopts large capacity rechargeable lithium battery pack.
With the unique strong anti-interference technology and stable testing capabilities in large distributed capacitance site (such as long cables) and strong electromagnetic interference environments (such as substations).
Touch colorful screen, and the test data will be displayed on the same screen. It is very convenient to test operation and view history record.
Custom setting measurement mode, optional PI and DAR calculation formulas, custom setting test voltage and custom setting test duration, which can provide variety of options to user and convient the special site request.
Voltage monitor: Automatically monitoring the live voltage of the measured object. when the voltage exceed 36V and will automatically prohibit to test to effectively protect the instrument and the operator.
Current monitor: Automatic display the current of test circuit
Temperature monitor: Automic display the temperature and humidity of tester inside.
Automatic discharge function, automatically and quickly release the electric charge of the measured object after the test, no need the external discharge circuit.
Large-capacity test record memory, test records can be directly browsed and analyzed in the tester. the tester can automatically store 1000 sets of real-time test data with test date and test time.
USB communication and upload function, the recorded data can be uploaded to the computer for stored statistical analysis.
Bluetooth communication function, can upload the test results to the mobile phone.
