Surge Arrester Counter Operation Tester | XHJS401
The XHJS401 surge arrester counter operation tester is specially developed by our technical staff to address the specific requirements of power users for on-site testing of lightning arrester discharge counters. It boasts a sleek appearance and is convenient to carry and use, making it an ideal replacement for the old, heavy testing instruments and inefficient testing methods.
The tester outputs a high-voltage pulse of 800 ~ 1000V to simulate a lightning discharge, verifying that the arrester counter operates and records correctly. With a compact body of only φ36×375mm and a total weight of 780g, the instrument can be held in one hand during overhead testing, and the telescopic conductive rod on the head can be extended to match the installation height of the counter.
Powered by four size-1 batteries (DC 6V), the XHJS401 supports more than 2000 discharge tests per battery set. The green and red indicator lights show the charging and ready states, and the test result is judged directly by whether the counter counts, giving an instant, intuitive verdict without any complex wiring or heavy auxiliary equipment.
Applications & Target Audience: Designed for substation maintenance teams performing electrical preventive tests, lightning protection testing institutions (meteorological lightning protection centers and third-party lightning protection inspection bodies), transmission line operation and inspection crews checking line arresters, quality control departments of zinc oxide arrester manufacturers, lightning protection inspection of gas stations and hazardous chemical sites, and electrical test teams of gas turbine and distributed energy stations.

Why Arrester Counters Must Be Tested
The discharge counter is the only visible indicator of whether a lightning arrester has operated. When lightning or an overvoltage strikes, the counter records the discharge action; without a working counter, maintenance staff cannot know whether the arrester has absorbed energy and whether its performance has degraded.
| Situation |
Risk |
XHJS401 Solution |
| Counter stuck or jammed |
Arrester discharge actions are not recorded, hidden failures cannot be found in time |
Inject 800-1000V pulse to verify the counter mechanism operates normally |
| Counter damaged by lightning |
Records are lost and arrester condition is unknown |
Quick on-site check confirms whether the counter needs replacement |
| Preventive test before thunderstorm season |
Untested arresters may fail under the next lightning strike |
Routine counter operation test per DL/T 596 preventive test regulations |
| New installation acceptance |
Counter wiring errors go undetected |
Acceptance test verifies the counter responds to a simulated discharge |
Operating Steps
Insert the ground wire into the tail of the instrument and make a firm connection
Adjust the length of the telescopic conductive rod on the head to fit the height of the counter
Rotate the power switch 90 degrees in any direction until a "click" is heard to turn on the power; the green light lights up
Wait for the red light to illuminate (roughly 3 to 5 seconds), indicating the instrument is ready
Touch the telescopic conductive rod to the test sample to start testing the arrester counter
Repeated testing is allowed without turning off the power, but the conductive rod must be separated from the test sample each time it charges
After finishing the test, turn off the power first, then discharge the head conductive rod to the tail ground wire before putting the instrument away
Safety Cautions
Always connect the ground wire firmly before use and discharge the head to the ground wire after testing
Do not touch the conductive rod or the test sample during the charging period
If the battery is low, the charging time will be extended; replace the batteries in a timely manner
Keep the instrument dry and avoid violent impacts during transport and storage
Only use the instrument for arrester counter operation testing as intended
FAQ
Q1: What is the XHJS401 arrester counter operation tester used for?
It is used to test whether the discharge counter of a lightning arrester operates correctly. The tester injects an 800 ~ 1000V high-voltage pulse to simulate a discharge, and if the counter counts, the counter mechanism is verified to be working.
Q2: How do I know if the arrester counter is working?
After the red ready light illuminates, touch the conductive rod to the counter terminal. If the counter advances one count, the counter is operating correctly; if it does not count, the counter may be stuck or damaged and needs repair or replacement.
Q3: How long does one test take?
The instrument is ready about 3 to 5 seconds after power-on. Each discharge test takes only seconds, and repeated testing is allowed without turning off the power, so a full bank of arresters can be checked quickly.
Q4: How many tests can the batteries support?
Four size-1 batteries (DC 6V) support more than 2000 discharge tests. When the battery is low, the charging time will be extended, and the batteries should be replaced in a timely manner.
Q5: Is it safe to test at height?
Yes. The 780g pen-style design and telescopic conductive rod allow one-hand operation at the counter installation height. Always connect the tail ground wire before use and discharge the head to the ground wire after testing before putting the instrument away.
