Hey there! As a supplier of Partial Discharge Testers, I've seen my fair share of issues that customers run into. Troubleshooting these testers can be a bit of a headache, but with the right approach, you can get to the root of the problem and get your tester back up and running in no time. In this blog, I'll share some tips on how to troubleshoot a Partial Discharge Tester.
1. Check the Basics
First things first, you gotta check the basics. Make sure the tester is properly plugged in and that the power switch is turned on. Sometimes, it's the simplest things that cause the most problems. Also, check the battery if it's a portable tester. A dead or low battery can lead to all sorts of issues.
If the tester has a display, see if it's showing any error messages. Error messages are like little clues that can point you in the right direction. Write down the error code if there is one, as it'll be useful when you're looking for solutions.
2. Inspect the Connections
Next, take a good look at all the connections. Loose or damaged connections can cause intermittent readings or no readings at all. Check the cables that connect the tester to the equipment you're testing. Make sure they're securely plugged in and that there are no signs of damage, like frayed wires or bent connectors.
If you're using probes, check their connections too. Sometimes, the probes can get loose or dirty, which can affect the accuracy of the readings. Clean the probes with a soft cloth if they're dirty, and make sure they're firmly attached to the tester.
3. Look for Interference
Interference can be a real pain when it comes to partial discharge testing. There are all sorts of things that can cause interference, like nearby electrical equipment, radio signals, or even fluorescent lights. If you suspect interference, try moving the tester to a different location. See if the readings improve.
You can also try using shielding cables or grounding the tester properly. Shielding cables can help block out external interference, and grounding the tester can reduce the risk of electrical noise.
4. Calibration Issues
Calibration is crucial for accurate partial discharge testing. If the tester isn't calibrated correctly, the readings won't be reliable. Check the calibration date of the tester. If it's been a while since the last calibration, it might be time to get it calibrated again.
Most partial discharge testers come with a calibration procedure in the user manual. Follow the procedure carefully to ensure accurate calibration. If you're not comfortable calibrating the tester yourself, you can always send it to a professional calibration service.
5. Software and Firmware
In today's digital age, many partial discharge testers have software and firmware that can affect their performance. Check if there are any software or firmware updates available for your tester. Sometimes, updating the software or firmware can fix bugs and improve the tester's performance.
To check for updates, visit the manufacturer's website. They usually have a section where you can download the latest software and firmware for your tester. Follow the instructions provided to install the updates.
6. Sensor Problems
The sensors in a partial discharge tester are what detect the partial discharges. If the sensors aren't working properly, you won't get accurate readings. Check the sensors for any signs of damage or wear. If you notice any damage, you might need to replace the sensors.
Some sensors can be cleaned to improve their performance. Refer to the user manual to see if the sensors can be cleaned and what cleaning method is recommended.
7. Compare with Known Good Equipment
If you're still having trouble troubleshooting the tester, try comparing it with a known good piece of equipment. If you have another partial discharge tester that you know is working properly, use it to test the same equipment. Compare the readings from the two testers.
If the readings from the known good tester are different from the readings from the tester you're troubleshooting, it's likely that there's a problem with the tester you're working on.


8. Seek Professional Help
If you've tried all the above steps and you're still unable to troubleshoot the tester, it might be time to seek professional help. You can contact the manufacturer's technical support team. They have the expertise and knowledge to help you diagnose and fix the problem.
When you contact the technical support team, provide them with as much information as possible. Include details about the problem, the error messages (if any), and the steps you've already taken to troubleshoot the tester.
