HIGH VOLTAGE DETECTOR ( 220V~500 KV ) ( HTC – HP-500 )

Description

The HTC HP‑500 High Voltage Detector is an advanced non‑contact safety instrument engineered for professionals working around live electrical systems—from low-voltage distribution to ultra–high-voltage transmission lines up to 500 kV. Designed for utility engineers, substation technicians, and field inspectors, this robust detector delivers fast, reliable voltage presence indication through manual range selection, making it ideal for live-line verification, fault tracing, and preventive safety inspections in demanding environments.

Voltage detection spans nine manual selectable ranges: 240 V, 3.3 kV, 11 kV, 33 kV, 66 kV, 110 kV, 220 kV, 330 kV, and 500 kV. The user rotates the range switch to match expected voltage level and simply brings the LED tip close to the conductor or equipment under test. When voltage exceeds the selected threshold, the unit emits both a bright LED flash and an audible buzzer—ensuring unmistakable detection even in noisy outdoor or industrial conditions.

Built with durability in mind, the HP‑500 meets IP65 protection standards, making it dust-tight and water-spray resistant—ideal for harsh outdoor installations or utility zones. It also features robust shockproof construction to withstand field rigors. The device is compatible with standard insulating rods, allowing safe operation from a distance when inspecting overhead conductors or live equipment.

Safety is paramount: the HP‑500 conducts a self-check at startup in Test mode, confirming both buzzer and LED functionality before detecting live application. The insulating rod must be properly attached before testing to ensure operator safety, as direct contact with the device is prohibited when it is active. Low-battery indication triggers when battery voltage drops near 5.5 V—ensuring reliable performance throughout field use.

Rated for frequency ranges between 40 Hz and 70 Hz, the HP‑500 performs across both standard power grid and industrial-frequency applications. Its maximum current draw is approximately 65 mA, powered by a single 9 V (6F22) battery housed securely in the unit. At a size of 115 mm × 15 mm × 69 mm and weight around 365 g including battery, it is lightweight and ergonomically designed for handheld or rod-mounted use.

Performance-wise, the HP‑500 provides a detection reminder distance of approximately 5 cm at 240 V, and up to 20 cm at higher kV levels—the closer the device tip, the more reliable the detection. This guidance helps to set safe testing distance while ensuring accurate voltage presence indication.
