240V to 500kV Voltage Detector

240V to 500kV (Includes Case and Shotgun Adapter)

No more checking against known voltage sources, truck ignitions, or separate field generating devices. You get automatic verification with each use and because of the flash and beep when the unit is turned on it will automatically remind the user to it off before storage maximizing battery life.

Non-Contact Voltage Detector Features

• Non-contact high voltage detector.
• Wide range of detection; finds 240V to 500kV; one instrument fit all applications.
• Eight switch-selectable voltage sensitivity ranges.
• Lightweight, minimizes sway at the end of long hot sticks.
• Audible and visual indication of live voltage.
• Self-test ensures that all system functions and indicators are working property by energizing the complete system.
• Designed for use with hot sticks incorporating a universal spline adapter.

Voltage Detector Applications

• Non-contact detection of live voltages.
• Check and detect live high voltage cables.
• Find faults in cables.
• Check grounding equipment.
• Service neon lighting.
• Trace live wires.
• Check high frequency radiation.
• Detect residual or induced voltages.

Units are intended for use in verifying the live or de-energized status of conductors, buss bars, and other types of exposed electrical equipment.

Use with rubber insulating gloves and/or hot sticks following company's safety work practices.

Voltage Detectors have a selector switch labeled with various voltage ranges. Models having URD settings are intended for use with capactive test points on URD elbows only. It will not provide reliable results nor is it recommended for use on shielded cable or cable with concentric neutrals.

Voltage detectors are calibrated to indicate within 8 to 10 inches of a conductor energized to the voltage switch setting. When verifying URD test points, URD switch settings are calibrated to indicate within 0.5 to 2 inches. The minimum system voltage for detection (URD 15kV setting) is 12,475 volts.

The 240V/Test switch position is intended to test the detector for its operational integrity, or to test 120/240 circuits.

Some difficulty may be encountered in situations where a lower voltage circuit is in the immediate vicinity of a higher voltage circuit, such as an overbuild parallel circuit. (The detector may respond to higher voltage line.)

In these situations turn the detector 90⁰ on the hot stick and approach the conductor from the side rather than from below. This angle of approach will be less sensitive to the electric field of the higher voltage circuit in the overbuild.

Operating Instructions

1. Check operational integrity of the detector. Switch to 240V/Test position and check in one of several manners.

• Place detector head, as marked, in close proximity to live wire outlet or equivalent, above 120 volts A.C. - detector will indicate.
• Rub the detector head, as marked, on clothing to obtain a static charge. Detector will indicate intermittently.
• Set switching at 240V or 4.2kV Overhead setting and place head of detector, as marked, against a spark plug lead of a running truck or auto engine - Detector will indicate.
• If an indication is not achieved using any of these methods, replace batteries and perform functional check again. If still no indication, notify your company for replacement unit or use another authorized method of checking voltage.

2. Select appropriate switch setting.

3. Move detector head progressively closer to the conductor until voltage is detected or until the head of the detector touches the conductor.

Note: if the presence of voltage is indicated by the detector do not move the detector closer to the conductor.

4. If no voltage is detected, repeat step 3 having selected the next lower voltage setting.

5. When a no voltage condition is determined, retest detector as in step 1 to verify the detector is working properly.

CAUTION: Use of this voltage detector should be restricted to trained personnel.

• Always follow approved safe work practices established by the safety officials of your company.
• Detectors should be used in conjunction with ASTM D-120 specification rubber gloves and/or ASTM F-711 hot sticks.
• Do not assume conductors are dead or will remain de-energized.
• Always install proper grounding devices before working on de-energized conductors.
• Application is limited to conductors, buss, and other types of exposed electric equipment. Shielded and underground conductors are excluded. Only use models with URD settings to check for voltage on underground elbows with capacitive test points.
