effect
A high voltage digital tester is a commonly used and essential instrument in industrial sectors such as power, postal and telecommunications, communication, electromechanical installation and maintenance, as well as the use of electricity as industrial power or energy. It is suitable for measuring the resistance values of various insulation materials and the insulation resistance of transformers, motors, cables, and electrical equipment.
Product Features
1. Exceptional Anti-Interference Performance: The device demonstrates a strong ability to resist electric field induction interference, with a capability of 2mA (50Hz), making it ideal for on-site insulation resistance measurements of 500kV transformers in 500kV substations without the need to disconnect wires.
2. High Short-Circuit Current: The typical short-circuit current is 10mA, making it well-suited for testing equipment with large capacity and high inductance.
3. Wide Resistance Measurement Range: It offers a broad resistance measurement range from 0.01MΩ to 1999GΩ, providing accurate readings with high resolution.
4. Versatile High Voltage Output: The device allows for voltage output selection at 0.5kV, 1kV, 2.5kV, 5kV, 10kV, or 15kV, and features smooth adjustments from 0V to the desired voltage level.
5. Audible and Visual Alerts: It includes a timer function to notify users to record and analyze the absorption ratio and polarization index of the tested object.
6. Superior Quality: The instrument utilizes imported high-quality components to ensure precise and reliable measurement accuracy.
7. User-Friendly: Featuring a compact and lightweight integrated chassis, it is easy to carry and simple to operate.
8. Durable and Attractive Design: Constructed from robust, highly durable materials, the instrument is built to last and maintain its appearance over time.
Safety precautions before the experiment
1. This instrument tests high voltage and strong output, and the measured object often has power frequency leakage or induced high voltage interference electrical energy. Therefore, for personal safety, it is necessary to first connect the safety grounding wire when using this instrument!
2. After starting the instrument under high voltage, please do not use manual discharge to check the instrument. After the test is completed, you should also wait for the instrument to automatically discharge and return the voltmeter to zero before performing routine manual discharge required for safety! Because the strong electrical pulse wave of short-circuit discharge damages the insulation life of the tested object, and if the pulse enters the instrument, it also damages the integrated circuit inside the instrument!
