What are the common problems with the live testing instrument for zinc oxide lightning arresters

During the use of the live testing instrument for zinc oxide lightning arresters, the following common problems may be encountered:

1. Power on and display issues

① No display or inability to power on:

Reason: The battery is dead or the instrument motherboard is faulty.

Solution: First, check the battery level and try connecting it to a power source to see if it can turn on. If it still cannot be turned on, it may be a fault with the instrument motherboard, and the manufacturer needs to be contacted for repair or replacement.

② LCD screen with or without display:

Reason: The battery is running low or the instrument CPU board is malfunctioning.

Solution: Check the battery level. If the battery level is sufficient, it may be a CPU board malfunction and the manufacturer needs to be contacted for assistance.

2. Battery and charging issues

① Battery cannot be charged properly or charging failure:

Reason: Instrument fuse burnt out, charging circuit failure, battery failure, etc.

Solution: Check if the fuse is burnt out. If it is burnt out, replace it with a fuse of the same model; Check if the charging circuit is functioning properly; If the battery fails, you need to contact the manufacturer to replace the battery.

② Battery depletion and damage:

Reason: If the instrument is not used for a long time (more than three months), the battery will be depleted and damaged.

Solution: The instrument should be charged every 3 months (for at least 6 hours) to ensure normal use.

3. Printing issues

Printer not printing or printing content layout error:

Reason: The thermal paper is not properly installed, the printer is malfunctioning, or the battery is running low.

Solution: Check if the thermal paper is installed correctly. If it is installed correctly, it may be a printer malfunction or the battery is running low. Contact the manufacturer for troubleshooting or battery replacement.

4. Operation and wiring issues

① Reverse connection of voltage and current signal input lines:

Consequence: If the current signal input line is connected to the PT secondary side or the measuring end of the test transformer, it may burn out the instrument.

Solution: When wiring, make sure that the voltage and current signal input lines are not reversed.

② Plug and unplug the measuring wire with input voltage and input current:

Consequence: It may burn out the instrument.

Solution: Do not plug or unplug the measuring wire when there is input voltage and input current.

③ Wiring error when taking reference voltage from PT secondary:

Consequence: It may lead to PT secondary short circuit accidents.

Solution: When taking the reference voltage from the PT secondary, the wiring should be carefully checked to avoid PT secondary short circuit.

5. Environmental and usage issues

① The instrument is placed in a damp or excessively hot environment:

Consequence: It may cause the instrument to become damp or damaged.

Solution: The zinc oxide lightning arrester tester should not be placed in high temperature or humid environments.

② Repair the damaged instrument by yourself:

Consequences: Improper operation may result in further damage to the instrument or cause safety accidents.

Solution: After the instrument is damaged, please stop using it immediately and notify the manufacturer. Do not open the box for repair by yourself.

The ZC-710B zinc oxide lightning arrester tester is a specialized instrument used to test the electrical performance of zinc oxide lightning arresters. This instrument is suitable for live or power outage detection of zinc oxide lightning arresters of various voltage levels, so as to timely detect dangerous defects such as insulation moisture and valve aging inside the equipment.

The instrument is easy to operate and easy to use, and the entire measurement process is controlled by the human-machine interface. It can measure the full current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of the zinc oxide arrester. The large screen can display the true waveform of voltage and current. The instrument utilizes digital waveform analysis technology and software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results. It can accurately analyze the content of fundamental and 3rd to 9th harmonics, overcome the influence of phase interference, and accurately measure the resistive current of the side phase lightning arrester.
