FAQ for Lightning Counter Tester

Q1: What is the main purpose of the Lightning Counter Tester?

A1: It generates simulated lightning impulse current to calibrate arrester lightning counters. It verifies the trigger sensitivity, counting accuracy and functional integrity of lightning strike recording devices installed on surge arresters.

Q2: What range of impulse current can this tester output?

A2: Its adjustable operating current ranges from 1A to 1000A, which covers the lightning current grades required for all conventional GIS equipment and substation arresters, with measurement error controlled within ±5%.

Q3: What is the minimum actuating current it can detect?

A3: The minimum trigger current is ≤0.5A, paired with a response time shorter than 10ms. It can accurately capture tiny transient lightning impulses under low-current lightning conditions.

Q4: Does it support both single-contact and dual-contact lightning counters?

A4: Yes. The tester is compatible with both single-contact and dual-counter types. The maximum counting capacity reaches 9999 times, and the counting value can be cleared manually anytime.

Q5: How long can the stored counting data be retained?

A5: Adopting EEPROM storage technology, all test data can be saved for more than 10 years without power supply.

Q6: Is the device suitable for harsh outdoor field environments?

A6: The whole machine reaches IP54 dustproof and waterproof rating. It supports working temperatures from -25℃ to +60℃ with built-in temperature compensation, ideal for cold regions and thunderstorm-prone areas. The anti-slip handle facilitates overhead working.

Q7: What data export methods are available?

A7: Equipped with RS485 and USB dual interfaces, test records can be exported conveniently to laptops. Optional on-site printing function is available for paper test reports.

Q8: How about the power supply configuration?

A8: Dual power supply design: built-in lithium battery supports over 8 hours of continuous field operation; AC220V external power input is available for long-time indoor calibration work.

Q9: Which mainstream brands’ GIS counters is it compatible with?

A9: It perfectly matches counter interfaces of ABB, Schneider and other international mainstream GIS gas insulated switchgear brands.
