In the process of testing an electrosensitive protective system, determining its response time is of crucial importance. A unique double penetration method of measuring electrosensitive protective device (ESPD) response time has been worked out in the Central Institute for Labour Protection. In the first step, low speed penetration enables the detection zone border to be localised. In the second step of measurement, the probe is injected at a high speed and response time is measured. Three different ways have been taken for validation of the method: theoretical analysis, calibration of the stand, and taking a series of measurements. The double penetration method enables ESPD response time measurement results to be obtained, the accuracy, repeatability, and reproducibility of which is satisfactory enough to be assessed objectively.
