DT70KV is a DC withstand voltage tester specifically designed for testing the dielectric properties of insulated gloves, with a maximum test voltage of up to 70 kVDC. The design of this device focuses on safety, adaptability, and ease of operation, and follows international standards such as ASTM D120, ASTM F496, and IEC 60903 (Attachment E) for regular testing of insulated gloves. It is widely used in the power industry, transmission and distribution companies, heavy industry, and fields involving electrical safety systems.
Multi standard compatibility and fully automated testingDT70KV basisASTM D120TheASTM F496-08AndIEC 60903 (Annex E)According to international standards, six glove grades of 00, 0, 1, 2, 3, and 4 are providedPre configured testing modeUsers only need to select the corresponding glove grade and set the maximum leakage current, and the device will automatically perform the complete dielectric strength testing process, and pass the test after the test is completedRed/green dual color LED indicator lightIntuitively display the judgment results of "pass/fail".
Multiple security guarantees and double-layer module designTo ensure the safety of high-voltage operations, the system iscontrol moduleandhigh voltage moduleComposed of two independent units. Both modules are equipped withEmergency stop switchIt is allowed to immediately cut off the power supply in emergency situations. The high-voltage module is also equipped withBuzzer alarmAnd set it upPower generation lock buttonProvide clear prompts at the beginning and end of the test and avoid misoperation. In addition, the equipment is equipped withAutomatic discharge functionAfter each measurement, safely discharge the test sample.
Intelligent remote control and data managementThis device supports the use ofAndroid based smartphones(BlueLogg application needs to be installed) for Bluetooth wireless remote control, which can help operators maintain a safe distance from high-voltage areas and improve testing safety. Meanwhile, the equipment providesUSB port, supportModBus communication protocolEasy to connect with PC for data transmission, or integrate equipment into a wider range of PLC automation testing systems. All test results can be stored in the built-in memory.
Durable, portable, and precise measurementThe instrument body is sturdy and has the ability to function when closedIP65Protection level, can effectively prevent dust and water, suitable for use in various environments on site. In terms of measurement performance, DT70KV canReal time display of output voltage and leakage current valuesThe leakage current resolution is 1 μ A, and the output voltage ripple is less than 2%, ensuring the purity and measurement accuracy of the high-voltage output.
