In experimental studies of HTS quench behaviors, different experimental protocols, especially heater configurations, including heater pulse duration and magnitudes, can lead to inconsistent measured results. In this work, mainly based on experimental measurements, the quench characteristics of REBCO samples, including minimum quench energy (MQE) and normal zone propagation velocities (NZPV), are investigated with various heater configurations. The relations between the measured quench characteristics and the heater configurations demonstrated that the measured MQE increased with the increasing heater pulse duration employed in the quench experiments, and the heater pulse duration had better be smaller than the diffusion time constant over minimum propagation zone; and the heater pulses adopted in the quench measurements for the stacks can be longer than that for the single tape.
