The LED may illuminate in a first color to indicate the detection of the AC voltage or the DC voltage and in a second color to indicate absence of the AC voltage and the DC voltage. The first color may correspond to red color. The second color may correspond to green color.

[0047] In some embodiments, the at least one illumination unit 108 may be configured to illuminate in red color upon detection of the presence of the AC voltage or the DC voltage, and in green color upon detection of the absence of the AC voltage and the DC voltage. The red color illumination of the at least one illumination unit 108 may correspond to a warning signal. The red color illumination of the at least one illumination unit 108 may alert the user that the AC voltage or the DC voltage may be present in the surrounding electric field.Docket No.: 81205.433.WOU1

[0048] In some embodiments, when no voltage is detected, the at least one illumination unit 108 may illuminate in the green color. The green color illumination of the at least one illumination unit 108 may indicate a safe environment. The green color illumination of the at least one illumination unit 108 may further indicate to the user that the circuit may not be energized. In some embodiments, the at least one illumination unit 108 may emit a bright light (e.g., the red color and the green color) that may cut through darkness. The bright light may ensure that the user may easily see voltage status even in poorly lit environments. The user may correspond to emergency responders, utility workers, and firefighters.

[0049] In some embodiments, the intensity of the first color of the at least one illumination unit 108 increases when a distance between the detector 100 and the AC source or the DC source decreases. In some embodiments, the intensity of the first color of the at least one illumination unit 108 decreases when the distance between the detector 100 and the AC source or the DC source increases. The intensity of the illumination of the at least one illumination unit 108 may depend upon the distance between the detector 100 and the AC source or the DC source. The intensity of the illumination of the at least on illumination unit 108 may allow the user to measure the proximity of the detector 100 with the AC source or the DC source. In some embodiments, as the detector 100 gets closer to the AC source or the DC source, the at least one illumination unit 108 may shine more brightly, indicating a stronger electric field and higher voltage detection. In some embodiments, as the detector 100 moves farther away from the AC source or the DC source, the intensity of the at least one illumination unit 108 may decrease. The decreasing intensity of the at least one illumination unit 108 may indicate the user that the user may be moving out of the range of potential danger and the voltage detection may be weakening.

[0050] In some embodiments, the detector 100 may further comprise a holder 116. The holder 116 may be configured to detachably couple a hot stick 300 (shown in FIG. 3) with the detector 100. The holder 116 may comprise a rib structure 118 comprising a plurality of radially arranged ribs 400 (as shown in FIG. 4). The hot stick 300 may allow the user to maintain a safe distance from the electrical source. The holder 116 may be coupled to the proximal end 110 of the gripper 102. The plurality of radially arranged ribs 400 may ensure a secure connection between the holder 116 and the hot stick 300. The plurality of radially arranged ribs 400 may be configured to prevent the detector 100 from becoming loose or detached from the hot stick 300 during the detection of the AC voltage or the detection of the DC voltage.Docket No.: 81205.433.WOU1

[0051] In some embodiments, operating the detector 100 from a distance may reduce the risk of electric shock or exposure to hazardous environments. In some embodiments, the holder 116 may be made from insulating materials. The insulating materials may ensure that no electrical current can pass through the holder 116. In some embodiments, the holder 116 may withstand high temperatures. The holder 116 may be coupled to the proximal end 110 of the gripper 102.

[0052] In some embodiments, the user working with high-voltage lines may use the detector 100 at a safe distance by attaching the detector 100 to the hot stick 300 via the holder 116. The hot stick 300 may be used where direct contact with the electrical system could be life-threatening. In some embodiments, the detector 100 may be configured to be positioned at the predefined angle relative to the AC source and / or the DC source. By angling the detector 100 at the predefined angle relative to the AC source and / or the DC source, the detector 100 may effectively capture strength of the electric field coming out from the AC source and / or the DC source. The positioning of the detector 100 at the predefined angle may also enhance visibility of the at least one illumination unit 108.

[0053] In some embodiments, the shell 104 may further comprise a shutter plate 122, the sensor plate 124, a motor 126, a controller 128, and a battery 130.
