Electrical maintenance professionals facing downtime losses and inefficient team coordination now have a groundbreaking solution: the Super Line Checker . This innovative device introduces live wire detection and single-operator functionality, transforming how electrical equipment is maintained and faults are diagnosed.

The Super Line Checker ’s standout feature is its ability to detect circuit breakers and distribution lines while they remain energized . Maintenance crews can now:

• Pinpoint faults without power interruption
• Drastically reduce downtime
• Minimize production losses during equipment upgrades or failures

Traditional line tracing often requires multiple technicians. The Super Line Checker ’s ergonomic design enables:

• Complete circuit breaker and distribution line detection by one operator
• Reduced labor requirements
• Lower personnel costs
• Enhanced work efficiency

Equipped with a standard clamp sensor, the device ensures:

• Accurate signal capture from live wires
• Elimination of false readings
• Broad voltage compatibility (AC/DC 12~528V)
• Adaptability to diverse field conditions

Beyond live circuit detection, the Super Line Checker performs:

• Dead line leakage detection: Locates ground faults in de-energized systems
• Buried wire tracing: Maps underground conduits in both live and dead states
• Cable identification: Tracks de-energized cable paths
• Circuit voltage verification: Checks 100V/200V/400V circuits

• Voltage range: AC 50/60Hz・DC 12～528V
• Signal frequency: 5kHz
• Dimensions: 112×82×30mm
• Weight: 111g

• Detection method: Magnetic field sensing
• Built-in dual coil sensors
• External clamp sensor compatibility
• Battery life: 8 hours (9V alkaline)
• Dimensions: 193×51×33mm
• Weight: 135g (including battery)

The Super Line Checker incorporates advanced signal processing that:

• Prevents signal leakage
• Eliminates circuit interference
• Holds NETIS certification (Registration No.: QS-200008-A)

1. Open panel door and position receiver above each breaker
2. Identify target breaker by maximum LED illumination
3. For ambiguous readings, use clamp sensor for confirmation

1. Switch suspected breaker to OFF position
2. Connect transmitter to identify leaking phase
3. Trace along wiring until signal diminishes at fault point

The device’s 5kHz signal transmission enables detection up to 5km between units. Wall penetration depth varies by material (typically ~1m). An optional signal leakage prevention accessory enhances performance in high-noise environments.

Unlike previous models, the current TLC-C version features improved noise immunity and a redesigned sensor interface. As a diagnostic tool rather than measurement equipment, the device requires no calibration.
