The invention relates to a current-to-voltage conversion tandem type clamp-free volt-ampere phase meter capable of measuring a small load, which is connected to a current transformer terminal in series by using precision resistors, converts small current signals into voltage signals, not only can measure the protection phasor of high-voltage electric power equipment under a small load and overcome a congenital defect of inability of measuring small current of a clamp type volt-ampere phase meter, but also removes a clamp of the clamp type volt-ampere phase meter and enables the measurement process to be more convenient and safer. The current-to-voltage conversion tandem type clamp-free volt-ampere phase meter provided by the invention solves a problem that a large quantity of loads required to be recognized to carry out phasor measurement on the high-voltage electric power equipment being electrified for the first time, and the accuracy of the protection phasor can be checked under a load condition of being far lower than 10% of a conventionally required load, thereby being capable of putting the equipment into operation as soon as possible. The current-to-voltage conversion tandem type clamp-free volt-ampere phase meter capable of measuring a small load not only can avoid the equipment from being damaged, but also can save a lot of electric energy, thereby ensuring safe operation of a power grid. The current-to-voltage conversion tandem type clamp-free volt-ampere phase meter capable of measuring a small load can be widely applied to the field of phasor measurement.
