A poloidal ring limiter was installed at one toroidal location in the OHTE device operated as a reversed field pinch. The ring acts as the solitary limiter beyond the smooth carbon tile vacuum vessel wall. The mere presence of the poloidal ring limiter broadens the current profile, rather than narrowing it by the reduced aperture, and raises the necessary one-turn voltage needed to sustain the current. The magnetic fluctuation frequency spectrum for both m = 0 and m = 1 poloidal modes is shifted to higher frequency in discharges with the ring limiter. The observed voltage increase is compared with that predicted by two recent edge helicity loss models.
