Measure High Current Without Large Clamp Jaws
Traditional rigid-jaw clamp meters can be difficult or impossible to use around:
- Large busbars
- Large-diameter conductors
- Parallel conductors
- Bundled cables
- Crowded switchboards
- Industrial feeders
- Main incoming supplies
The UT281E+ solves this problem using a 1100 mm flexible current sensor.
The flexible coil can be routed around large or awkwardly positioned conductors, providing a practical way to measure high AC currents without disconnecting the circuit.
Up to 10,000 A AC Current Measurement
The UT281E+ provides AC current measurement across multiple ranges up to approximately:
9.99 kA / 10,000 A
This makes it particularly useful for high-current electrical installations where standard 600 A or 1000 A clamp meters may not provide sufficient measurement capability.
Typical applications include:
Main Switchboards | Industrial Feeders | Busbars | Large Motors | Transformers | Distribution Systems | Solar PV | Electrical Infrastructure
1100 mm Flexible Coil
One of the major advantages of the UT281E+ is its 1100 mm-long flexible coil.
The coil can accommodate a conductor area of approximately 350 mm diameter, providing significantly greater installation flexibility than conventional clamp meters.
This makes it particularly useful when measuring:
- Large single-core cables
- Multiple parallel cables
- Busbar arrangements
- Transformer conductors
- Large switchboard feeders
- Industrial power distribution
- Solar PV AC feeders
- Generator outputs
True RMS Measurement
Modern electrical systems frequently contain non-linear loads that produce distorted current waveforms.
The UT281E+ uses True RMS measurement, providing more representative AC current and voltage measurements where waveforms are not purely sinusoidal.
This is useful when working with loads such as:
- Variable-speed drives
- Switching power supplies
- Industrial electronics
- UPS systems
- Inverters
- Solar PV systems
- Modern electrical equipment
