PURPOSE: A device for constructing a bypass power line is provided to easily construct a bypass power line by using a spare power line when a leakage current is generated in the power supply system of a street light lamp. CONSTITUTION: A power line(100) includes two main lines and a single preliminary line. A pole controller(400) is connected to the power line in parallel. The pole controller transmits a signal to a streetlight control container through a local area communications when a leakage current is generated. A street light control container(200) controls the on/off state of a street light through local area communications with the pole controller. The streetlight control container applies power by using a preliminary line when a leakage current is generated. A central control center(600) informs an administrator of the generation of the leakage current.

Apparatus for making a detour of power line on the leakage current

Street lighting equipment for a remote energy saving system is provided to save a time taken to check the state and a failure of a streetlight and a time taken for A/S and to save a maintenance cost of the street lighting equipment by extending a lamp life time. A remote streetlight control system includes a main control device, a streetlight controller(30), and street lighting equipment(40). The street lighting equipment for a remote energy saving system includes a sixth transmitting and receiving member(41), a ballast(43), an ignitor(44), and a state collecting member(42). The main control device wirelessly transmits a streetlight control signal for controlling plural streetlights and wirelessly receives streetlight state data. The streetlight controller transmits the streetlight control signal and the state data received from the main control device. The street lighting equipment controls a high-voltage discharge lamp according to the control of the streetlight controller. The ballast can adjust an output power by adjusting a coil tap. The ignitor generates a high voltage for initial ignition. The state collecting member detects and collects the states of the ballast, the ignitor, and the high-voltage discharge lamp.

A remote control energy saving device for a streetlight is provided to check the state of insulation resistance and recognize the opening and closing of a control box door by integrally connecting switches of insulation resistance testers to measure the insulation resistance between a cable and the ground or between the cables. An insulation resistance tester(37) measures the insulation resistance and a leakage current between power cables connected to a plurality of streetlights(40) having high voltage discharge lamps(45), and the ground. A state collecting device(38) collects the state of the plurality of streetlights having the high voltage discharge lamps with a predetermined spectrum. A power factor automatic controller(39) minimizes the reactive power of the cables connected to the plurality of streetlights to automatically adjust a power factor.
