Product DescriptionProduct DescriptionPRODUCT FUNCTIONNRG120 120kv/5mA DC hipot testerFunction1,DC Hipot Tester adopts high frequency PWM technology to make closed adjustment with high voltage stability, small ripple factor and fast reliable protection circuit. The generator can endure direct discharge by devices of large capacitance. It is of small size and of light weight, convenient for field use.2,Full range of linear smoothly adjusted voltage, with voltage regulation accuracy smaller than 0.1%; voltage measurement accuracy is 0.5%, resolution 0.1kv; Current measurement accuracy is 0.5%, the minimum resolution: control box 1μA, shock resistance current 0.1μA.3,The generator uses AC 220 V power supply (AC220V±10%, 50 hz±1%), the ripple factor is less than 0.5%, and can be used for all-weather at the site .4,High voltage multiplier uses Dupont materials for full solid encapsulation, overcoming the inconvenience brought by the air and oil filled equipment. Broad base and outer cylinder of light quality makes it stand steadily and more convenient for maintenance.5,75% MOA voltage switch button, simple and convenient testing arrester.6,Over-voltage setting function displays the over-voltage value during regulation process; perfect protection against discharge of over-voltage, over-current and short circuit. This is the best companion for cable experiments.7,Perfect break line and non-zero potential start protection function protects the operator and samples at any time. This product has overall design of shock-proof control box, concise, clear panel design and voice prompt for operation.Technical ParametersVoltage (KV)/Current (mA)Control BoxHigh-Voltage UnitRatedVoltageSize (mm)Weight kgSize (mm)Weight kg120/5120KV310 * 250 * 2305kg625* 260 * 22010kgoutput polarityNegative polarity, no-voltage start, linear continuous adjustmentworking power supply50HZ AC220V±10%voltage error0.5%±2,minimum solution 0.1KVcurrent error0.5%±2,minimum solution 0.1μAripple factorbetter than 0.5%voltage stabilityRandom fluctuationworking mannerInterval working, less than 30 minutes under rated loadworking conditionTemperature: 0-40℃, humidity: less than 90%storage conditionTemperature:-10℃-40℃, humidity: less than 90%altitudeLower than 3000 mPRODUCT APPLICATIONCompany ProfileABOUT USRefine On (Hebei) Electric Power Technology Co., Ltd. is located in the Mancheng High-tech Development Zone, Baoding.

Insulating Oil Tester Series1.1 What is the main function of the Insulating Oil Dielectric Strength Tester (80kv/100kv)?Tests insulating oil's dielectric strength to detect impurities, moisture, or aging, ensuring safe operation of transformers and circuit breakers.1.2 How often should the Insulating Oil Dielectric Strength Tester be calibrated?At least once a year; shorten intervals for frequent use, harsh environments, or post-maintenance.1.3 What is the difference between the Closed Cup Flash Point Automatic Tester and the Open Cup Flash Point Automatic Tester?? Closed Cup: Tests in sealed containers; for low-flash oils (e.g., diesel) and sealed power equipment.? Open Cup: Tests in open containers; for high-flash oils (e.g., insulating oil) and air-exposed scenarios.2. Transformer Test Series2.1 What can the Transformer Capacity Tester detect?Detects transformer's actual capacity, no-load/load loss, no-load current, and impedance voltage; judges compliance and faults.2.2 How to use the Transformer Tap Changer Tester?1. Connect test lines to tap changer terminals per manual.2. Power on, select test mode (e.g., resistance test).3. View results; disconnect and power off after. (Note: De-energize and ground transformer first.)2.3 What is the purpose of the Transformer Winding Deformation Tester?Detects winding deformation (axial displacement, short circuits) from short-circuits or vibration; enables early maintenance to avoid accidents.FAQ3. Circuit Breaker Test Instruments3.1 What are the differences between the Single-Chip Microcomputer and Industrial Computer Circuit Breaker Characteristic Testers?? Industrial Computer: Stronger data processing, more tests (e.g., dynamic resistance), touch interface, and computer data communication.? Single-Chip: Simple structure, low cost; for basic characteristic tests.3.2 How to judge whether the Circuit Breaker Characteristic Tester is working normally?1. Check power and indicator lights.2. Run self-test; test a standard circuit breaker.3. Confirm results are within allowable error. Stop use if self-test fails or errors are large.4. Cable Fault Test Instruments4.1 What types of cable faults can the Multiple Pulse Cable Fault Tester detect?Detects low-resistance (short circuits), high-resistance (leakage), and open-circuit faults; locates faults via pulse reflection.4.2 How to improve the accuracy of the Cable Fault Location Tester?? Ensure correct, firm test line connections.? Select proper test mode/parameters for fault type.? Eliminate environmental interference; keep site clean/dry.? Calibrate regularly.? Test multiple times for complex faults; analyze results comprehensively.5. Insulation Resistance Tester5.1 What is the application scope of the High-Voltage Insulation Resistance Tester?Tests insulation of high-voltage equipment (transformers, generators, cables, etc.); checks for moisture, dirt, or aging to support commissioning and maintenance.5.2 How to (complete based on full content; core steps?Store in dry environment, avoid impact; clean terminals before use; calibrate regularly to maintain accuracy.)
