FAQ

FAQ

1. Insulating Oil Tester Series
1.1 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 Series
2.1 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.

FAQ

3. Circuit Breaker Test Instruments
3.1 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 Instruments
4.1 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 Tester
5.1 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.)
