Zinc Oxide Arrester Testing
The ETCR 9400 is a clamp tester designed to measure leakage current on zinc oxide arresters operating on circuit lines below 35kV. It performs live testing without interrupting the power supply or removing the arrester from service.
Live-Line Maintenance Teams
Technicians who need to assess arrester condition on energised lines will find the 30 m wireless communication and 200-group data storage useful for efficient field work. Buyers who require an integrated display on the clamp head or a measurement range extending beyond 300.0 mA should look at alternative instruments.
0.000 mA to 300.0 mA Measurement Range
This span, with 1 µA resolution and ±1% rdg ±8 dgt accuracy, determines whether the tester can detect the low-level leakage currents that indicate early arrester deterioration. The F40 mm clamp aperture sets the maximum conductor size that can be accommodated.

Questions about this item
What power source do I need to supply myself for the ETCR 9400 to operate?
The tester requires batteries that are not included in the package; you must purchase them separately from a local store.
Can I test arresters on a live 35kV line without shutting down the circuit using the 9400?
Yes, the clamp tester measures leakage current on energised lines up to 35kV with no need to de-energise or remove the arrester.
How do I confirm the 9400 is capturing readings correctly after I clamp it on?
The display will show a leakage current value within the 0.000mA to 300.0mA range at 1µA resolution, and each measurement can be saved to one of 200 storage groups.
