The present invention relates to a system for measuring insulation deterioration of a power cable. The system includes: a feeder cable terminal which is connected to a cable grounding line of the power cable; a toggle switching unit which switches grounding connection of the cable grounding line, in which one end portion switches connection to the feeder cable terminal, and in which the other end portion is grounded; and a water tree switching unit which switches electrical connection between one end portion of the toggle switching unit and an external connection terminal. Therefore, the system for measuring insulation deterioration of a power cable can utilize a space in an existing console box of equipment, an online cable monitor (OLCM) for example, and convert a mode into a water tree measurement mode in an easy manner by switching a mode into the water tree measurement mode or an OLCM mode with the OLCM even without additional equipment. |
