Driven by the need for traceable measurement methods, LNE has developed and characterized new reference measurement systems for the calibration of HV impulses, including lightning impulses (1, 2 µs/ 50 µs) and switching impulses (250 µs/ 2500 µs), according to new requirements of IEC 60060-1 and IEC 60060-2. This paper describes new reference measurement systems, which have been developed and fully characterized at LNE. In addition, the paper describes the test procedure for accurate measurements especially for in-situ calibrations in 5 successive steps; measurements of radiofrequency disturbances, step response of voltage dividers, measurement of the scale factors of voltage dividers, calibration of digitizer’s channels and ranges, measurement of the voltage linearity of the divider under calibration up to maximum voltage.

We present observations of X-rays from laboratory sparks created in the air at atmospheric pressure by applying an impulse voltage with long (250 µs) rise-time. X-ray production in 35 and 46 cm gaps for three different electrode configurations was studied. The results demonstrate, for the first time, the production of X-rays in gaps subjected to switching impulses. The low rate of rise of the voltage in switching impulses does not significantly reduce the production of X-rays. Additionally, the timing of the X-ray occurrence suggests the possibility that the mechanism of X-ray production by sparks is related to the collision of streamers of opposite polarity.

Reset Control

Reset controllers consist of two parts—a linear compensator and a reset element. The linear compensator is designed, in the usual ways, to meet all closed-loop performance specifications while relaxing the overshoot constraint. Then, the reset element is chosen to meet this remaining step-response specification. In this paper, we consider the case when such linear compensation results in a second-order (loop) transfer function and where a first-order reset element (FORE) is employed. We analyze the closed-loop reset control system addressing performance issues such as stability, steady-state response, and transient performance.
