In order to ensure that the overhead line is not LIVE before earthing, a safety device called the over voltage detector is utilised. Before performing maintenance on ac circuits, switches, and outlets, it is quick and affordable to check with voltage detectors to see whether there is live voltage present.
They clip onto a shirt pocket and beep or light when they detect voltage on exposed conducting elements or through insulation. They are also known as voltage wands, sticks, “power sniffers,” or pens.
These voltage detectors are made to monitor voltage on electrical circuits in residential, commercial, and industrial facilities without making contact with the circuits themselves.
As long as the detector is rated adequately for the voltage level and electrical safety category in which it will be utilised, incidental contact with live electrical conductors is not a problem. The user must also follow safe work procedures.
The Global Over Voltage Detectors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Voltage detectors from the Pfisterer KP-Test 5 Series are available in a variety of specifications as resistive double pole voltage detectors from 500V to 4,000V or capacitive single-pole voltage detectors for a.c. voltages from 1V to 420kV:Type S KP-Test 5 dual: For medium voltage (MV) applications with contact electrode extension and nominal voltage range selector – nominal voltages from 3 to 33kV/36kV, KP-Test 5: For medium voltage (MV) switchgear and electrical equipment applications with contact electrode extension – nominal voltages from 1 to 33kV/36kV Type L KP-Test 5L dual: Mainly for use on medium voltage (MV) overhead lines with nominal voltage range selectable – nominal voltages from 3 to 33kV/36kV, and Type S KP-Test 5L: Mainly for use on medium voltage (MV) overhead line systems.
