About Non contact High Voltage Detector (Arm Type)

The Metravi AT500 high-voltage detector is a handy, wearable instrument, which reminds the electrical worker to pay attention to safety and avoid high voltage electric shock accidents.
When the operator is wearing the alarm and gets close to a high voltage charged body within a certain distance, sound and light alarms go off, according to the safety distance of the corresponding voltage level.

This instrument can also be used for line fault detection and electroscope. Works only for single-core cables. Will not work for shielded/armoured cables.

Advanced Safety and Detection

This detector is engineered to meet the rigorous demands of high-voltage environments, offering CAT IV insulation for optimal safety. Audible and visual indicators clearly alert the user to live voltage, reducing workplace risk. Its factory calibration, precise accuracy (10%), and IP54 protection ensure dependable performance in challenging conditions.

Ergonomic and Portable Design

Built with lightweight ABS plastic and an extended 370 mm arm, this handheld tool ensures comfortable operation and allows safe distancing from energized sources. Its compact dimensions and 300 g weight make it easy to carry, while the robust construction withstands regular field use.

User-friendly Operation

The detector is manually operated and instantly signals the presence of live voltage with quick response (< 1 second). Coupling LED and buzzer alarms provides immediate, unmistakable feedback. With a long battery life and rapid response, it enhances safety for routine checks and emergency interventions.

FAQ's of Non contact High Voltage Detector (Arm Type):

Q: How do I operate the Non-contact High Voltage Detector (Arm Type)?

A: To use the detector, manually extend the arm and bring the sensing tip near the suspected live high voltage AC line. If live voltage is detected, the red LED will illuminate and the buzzer will sound. Always maintain a safe distance as indicated by the device for each voltage range.

Q: What conditions can this detector withstand during operation and storage?

A: The device operates reliably within temperatures of -10C to +50C and can be safely stored between -20C to +60C. It is protected up to IP54 and operates in humidity up to 80% RH, making it suitable for a wide range of environmental conditions.

Q: When should the battery in this voltage detector be replaced?

A: A standard 9V DC battery powers the device, offering approximately 100 hours of continuous use. Replace the battery when the device no longer provides reliable indication or when extended battery runtime is required for frequent operations.

Q: Where is this high voltage detector typically used?

A: This detector is widely used in power plants, substations, maintenance sites, and by utility service personnel across India for routine inspections, emergency safety checks, and before commencing electrical work on high voltage lines.

Q: What is the process for ensuring the device's calibration and accuracy?

A: The device is factory calibrated to provide 10% measurement accuracy and 1 kV resolution across its 1 kV to 132 kV range. No additional user calibration is necessary; simply ensure proper maintenance and battery replacement for ongoing accuracy.

Q: How does the detector indicate the presence of live voltage?

A: The Non-contact High Voltage Detector signals live voltage with a red LED light and an audible alarm (buzzer). Both alarms provide clear and immediate notification to the user, aiding quick and safe decision-making during inspections.

Q: What are the key benefits of using this non-contact, arm-type detector?

A: Key benefits include enhanced user safety through non-contact detection, reduced risk during high voltage work, ease of handling due to its extended arm, and instant, dual-mode alarms for rapid voltage status identification.
