The invention relates to the power equipment field, especially to a power cable accessory fault simulation module and a simulation apparatus with the same. The simulation apparatus comprises a fault simulation module, a power supply module, and an electrode module; the electrode module and the fault simulation module are in contact and connected detachably; and the power supply module provides a high voltage for the electrode module, so that partial discharging is carried out on the fault simulation module in contact with the electrode module. With the fault simulation module, a finished product cable accessory is simulated to carry out testing and common fault defects of the cable accessory can be set manually; and the electrode module simulates the wiring terminal of the cable accessory and the power supply module simulates the cable voltage. Installation of the cable accessory and the cable body by the technical professionals is not required, so that the manpower and materials are saved and lots of resource wasting can be avoided. A technical problem that the cost is high because the finished cable accessory is used as a testing product during the testing process of the existing partial discharge detection system can be solved.
