TESCO Metering Launches Innovative Voltage Detector for Worker Safety

TESCO Metering has introduced a new safety device aimed at protecting transit and utility workers in hazardous electrical environments. The company unveiled the 4E2-1 Third Rail Voltage Detector, a specialized instrument designed to detect electrical potential between energized third rail systems and ground. This launch underscores the growing need for enhanced worker safety measures in increasingly complex rail and utility systems.

Advanced Features Enhance Safety

The 4E2-1 is specifically targeted at transit authorities and utility companies that require immediate voltage confirmation during inspection, maintenance, and testing operations. As electrical systems operate at higher voltages, the risk to workers escalates, particularly around third rail systems. TESCO Metering aims to address this concern with a device that delivers unmistakable feedback to ensure technician safety before they commence work.

This detector employs two independent circuits equipped with high-visibility LED indicators to confirm the presence of voltage. Additionally, it features a built-in audible alarm, which provides an extra layer of situational awareness for workers on-site. The instrument operates on both alternating and direct current systems, supporting voltages up to 1,500 volts. Its design allows for testing at distances of up to four feet, significantly reducing worker exposure to potential hazards.

Designed for Harsh Conditions

The 4E2-1 is constructed to withstand challenging field conditions. It features a moisture- and oil-resistant phenolic handle and housing, sealed internal electronics, stainless steel prod tips, and an integrated rubber hand guard, all of which contribute to safe handling. This rugged construction ensures that the device can maintain performance even in demanding environments.

According to TESCO Metering, the 4E2-1 was developed specifically for electrified rail and high-voltage utility settings. It is already in operation with systems such as Bay Area Rapid Transit, demonstrating its practical application in real-world scenarios. The company emphasizes that the robust design and redundant detection capabilities allow operators to quickly and confidently verify voltage conditions prior to entering hazardous work zones.

Tom Lawton, president and chief executive officer of TESCO Metering, stated, “Working around high-voltage infrastructure leaves no margin for uncertainty.” He emphasized that the detector is engineered to provide clear, reliable confirmation of voltage presence, enabling workers to make informed safety decisions before undertaking tasks.

This new device reinforces TESCO Metering’s commitment to safety solutions for critical infrastructure. Accurate voltage detection is vital, as it can mean the difference between routine maintenance and potentially catastrophic injury.

As electrical environments continue to evolve, innovations like the 4E2-1 Third Rail Voltage Detector represent a significant step forward in ensuring the safety of workers in the field. With its advanced features and robust design, this device is set to become an essential tool for transit and utility professionals.
