A reversed field pinch configuration with a quadra-null toroidal divertor has been sustained for a much longer time than the magnetic diffusion time on the TPE-2M device. By applying toroidal divertor fields, the plasma resistance has been reduced by 40% in low plasma current operations (40-55 kA), along with a decrease in the line emission of light impurities and limiter materials (molybdenum). Direct measurement of internal magnetic fields by inserted magnetic probes has shown that a separatrix exists within the limiter radius. Though the behaviour of the slow magnetic fluctuations has not deteriorated, fast and spiky m=0 mode fluctuations have been excited, especially near the reversal surface
