Product Overview
The YLBL-8022 Zinc Oxide Surge Arrester Live-Line Tester is a specialized instrument designed to test the electrical performance of zinc oxide surge arresters. This instrument is suitable for live-line or de-energized testing of zinc oxide surge arresters at various voltage levels.
Key Features & Advantages
1. Safe and Reliable: The instrument carries only low-voltage current internally, with a voltage not exceeding 8.4 V; the current and voltage sensors are fully isolated, ensuring safety and reliability.
2. Selectable Voltage Reference Methods: Supports using the three-phase or Phase B voltage as the voltage reference; supports using an induction plate to measure the Phase B electric field strength as the voltage reference (optional), which facilitates voltage sampling; supports measuring the voltage at the maintenance power terminal box (busbar-related).
3. Selectable Current Sampling Methods: Leakage current can be sampled by connecting wires to both ends of the surge arrester counter, or by using a current clamp to measure the leakage current in the surge arrester's grounding wire (optional).
4. Standard anti-interference processing: Includes anti-interference calculation and angle compensation functions, completely resolving three-phase mutual interference-a requirement for 220 kV and higher voltage levels.
5. Built-in lithium battery: Comes standard with a high-capacity lithium-ion battery, making it particularly suitable for locations without a power source.
6. High-speed sampling: High sampling frequency, advanced digital signal processing technology, strong anti-interference performance, and extremely high measurement accuracy.

FAQ
Q: Where can zinc oxide arresters be applied?
A: Distribution networks, substations, transformers, overhead lines, wind / solar power stations, railway traction systems. Suitable for AC systems ≥1kV.
Q: Can ZnO surge arresters be used in DC systems?
A: Specialised DC-type surge arresters must be used. Standard AC surge arresters cannot be used directly to protect DC systems.
