Arrester test equipment

Product description

Instrument Usage

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 various voltage levels of zinc oxide lightning arresters, in order to timely detect dangerous defects such as insulation moisture and valve aging inside the equipment.


Performance characteristics

• Color touch screen: 800 × 480 7-inch high-definition color touch screen, human-machine dialogue.

• Multiple synchronization methods: supports wired synchronization (with voltage); There are two synchronization methods for finding voltage reference through software calculation without voltage.

• Compatible with live and power outages: suitable for use in places such as live, power outage, or laboratory environments with lightning arresters.

• Large range acquisition: voltage acquisition range 0-250V, current acquisition 0-20mA.

• Simulated three-phase testing: Testing A, B, and C three-phase zinc oxide lightning arresters in three stages can be saved as a set of test data.

• Safe and reliable: The instrument only carries weak current internally, and the voltage does not exceed 8.4V; The current and voltage sensors are completely isolated, ensuring safety and reliability.

• Optional voltage method: Support taking voltage reference as voltage reference; Support the use of an induction board to take the electric field strength as a voltage reference (optional), which facilitates voltage sampling; Support maintenance of power terminal box voltage (bus related).

• Optional current method: You can use a wire connected lightning arrester counter to sample the leakage current at both ends, or you can use a current clamp to collect the leakage current of the grounding wire of the lightning arrester (optional).

• Built-in lithium battery: Standard with high-energy lithium-ion battery, especially suitable for situations without power supply.

• High speed sampling: High speed sampling frequency, advanced digital signal processing technology, strong anti-interference performance, and extremely high measurement accuracy.

• Built in calendar clock: Built in calendar clock provides time basis for printing and saving data.

• Massive storage of experimental data: This machine is equipped with large capacity storage to store massive amounts of data. It has data storage and browsing functions, as well as power failure protection function.

• U disk export test data: Equipped with U disk export data function, exporting Word files.

• Bluetooth control and uploading data: optional Bluetooth function, equipped with Android Bluetooth APP, can be installed on a mobile phone or tablet to control, upload, and generate Word files.

• Convenient background color switching: You can set the screen color, which can be changed to a patterned blue background or a patterned black background. You can also set the background brightness, standby brightness, and standby time.

• Built in training materials: The screen is equipped with various wiring methods to guide on-site use.

• Chinese input of test information: Relevant sites, equipment, personnel, notes, etc. can be input in Chinese, making it easy to identify, save, and print test data.

• Switch between Chinese and English: You can directly switch between Chinese and English interfaces, compatible with Chinese and foreign usage scenarios (optional).

• Convenient to carry: The host is a handheld device with an integrated dustproof and anti-corrosion chassis, which is small in size, light in weight, and easy to carry.
