Lightning protection tester overview

The ETCR 3800B tests the performance parameters of lightning protection components including metal oxide varistors and gas discharge tubes. It measures insulation resistance, polarization index, and dielectric absorption ratio. A touch colour screen provides the operator interface.

Suitable users and limitations

Electricians and technicians who need to verify surge protectors, lightning arresters and varistors will find the required test functions. The instrument covers initial action voltage from 50 to 3000 V and leakage current up to 1000 µA. Buyers who require testing of other component types or higher voltage ranges should look at alternative equipment.

Key measurement ranges

Initial action voltage and DC breakdown voltage are both tested from 50 to 3000 V. Leakage current measurement spans 0 to 1000 µA. Insulation resistance is measured from .5 to 10 GΩ. These ranges decide whether the tester matches the specific protection devices being evaluated.

Questions about this item

What test leads or probes are included to connect the ETCR 3800B to a varistor or discharge tube?

The tester ships in a single box with the instrument and the high-voltage leads needed for MOV and GDT measurements.

Which step is most often missed when setting up the ETCR 3800B for a DC breakdown voltage test on a gas discharge tube?

Selecting the qualified-range limits before pressing the test button; the instrument will not flag a pass or fail until those limits are stored.

After how many years should the ETCR 3800B be returned for recalibration to keep the 50–3000 V and 0–1000 µA ranges accurate?

The manufacturer specifies a three-year parts cycle, so plan to send the unit for recalibration at the three-year mark.
