Precision Power Calibration

The Transmille 3310A is specifically designed for calibration of instruments that measure electrical power.

Power calibration is more complex than conventional voltage or current calibration because voltage and current must be generated simultaneously.

The phase relationship between the two signals must also be accurately controlled.

By combining these functions in one system, the 3310A provides a convenient reference source for professional power measurement calibration.

Voltage and Current Generation

The Transmille 3310A generates voltage and current simultaneously.

Voltage output extends to:

1000 V

while current output extends to:

30 A

This provides sufficient direct output capability for a broad range of power meters, analyzers and electrical measurement equipment.

Generating both quantities from the same calibration platform simplifies the measurement setup and allows their phase relationship to be accurately controlled.

AC and DC Power Calibration

The Transmille 3310A supports both AC and DC power applications.

For DC power calibration, voltage and current are generated simultaneously without the phase relationship required for AC measurements.

For AC power calibration, the instrument generates controlled sinusoidal voltage and current signals.

This allows the same calibrator to cover a broad range of electrical power measurement equipment.

Adjustable Phase

One of the key capabilities of the Transmille 3310A is adjustable phase.

The phase relationship between voltage and current can be set through:

0° to 360°

This allows the calibrator to reproduce different load conditions.

A phase angle of 0° represents an ideal resistive load, while other phase settings can simulate inductive or capacitive load conditions.

This capability is essential for evaluating the performance of power meters under different operating conditions.

Power Factor Calibration

The adjustable phase relationship allows the Transmille 3310A to generate different power factors.

Power factor is an important measurement parameter in AC power systems and is defined by the phase relationship between voltage and current for sinusoidal signals.

By varying the phase angle, instruments can be tested at:

unity power factor

as well as:

leading and lagging power factors

This enables more comprehensive calibration than a simple voltage and current test.

Active Power Calibration

Active power represents the electrical power actually transferred to a load.

For sinusoidal signals, active power is determined from voltage, current and the cosine of the phase angle.

The Transmille 3310A controls all three quantities required for this measurement.

This makes the calibrator suitable for verification of active power measurement functions in:

• Power meters
• Power analyzers
• Wattmeters
• Electrical test equipment
• Energy measurement systems

Apparent Power Calibration

Apparent power is determined from the RMS voltage and RMS current without applying the power factor.

The Transmille 3310A can provide the simultaneous voltage and current signals required to test apparent power measurements.

This is particularly useful for multifunction power analyzers that display active power, apparent power and power factor simultaneously.

Reactive Power Applications

Reactive power measurement depends on voltage, current and their phase relationship.

Because the Transmille 3310A provides adjustable phase control, it can be used in calibration procedures involving reactive power measurement.

This extends the calibration workload beyond basic wattmeter testing.

Frequency Control

The Transmille 3310A provides frequency control for AC power calibration.

Power applications can be tested over frequencies up to approximately:

1 kHz

depending on output conditions and configuration.

This enables power measurement equipment to be evaluated not only at standard mains frequencies such as 50 Hz and 60 Hz but also at other frequencies within its operating range.

This is particularly useful for industrial, aerospace and specialist electrical measurement applications.

Calibration of Power Meters

Power meters are one of the primary applications for the Transmille 3310A.

The calibrator can generate known voltage, current, frequency and phase conditions.

The displayed value of the device under test can then be compared with the reference value generated by the calibrator.

Different test points can be selected across the operating range of the power meter.

This allows evaluation of linearity and measurement performance across different voltage, current and power factor conditions.

Calibration of Power Analyzers

Modern power analyzers measure significantly more than voltage and current.

Typical functions include:

• RMS voltage
• RMS current
• Active power
• Apparent power
• Reactive power
• Power factor
• Frequency
• Phase

The Transmille 3310A provides the fundamental electrical signals required to evaluate many of these functions.

This makes it a useful calibration source for professional power analysis equipment.

Energy Meter Applications

Electrical energy is calculated from power over time.

A stable and accurately controlled power source is therefore essential when testing suitable energy measurement equipment.

The Transmille 3310A can provide controlled voltage, current and phase conditions for energy-related calibration applications.

This allows laboratories to expand their electrical calibration workload beyond conventional multimeters and power meters.

Clamp Meter Calibration

The Transmille 3310A can also be used for calibration of current clamps and clamp meters.

The standard current output provides up to 30 A directly.

For clamp meters requiring significantly higher currents, optional current coils can multiply the effective current passing through the clamp.

A multi-turn current coil works by passing the generated current through the clamp several times.

For example, a 50-turn coil supplied with 20 A creates an effective ampere-turn value corresponding to:

1000 A

This principle allows high-current clamp meter ranges to be tested without generating the equivalent current directly through a single conductor.

Current Coil Accessories

Transmille offers current coil solutions for use with its electrical calibration systems.

These accessories are particularly valuable for laboratories calibrating:

• AC clamp meters
• DC clamp meters
• Current clamps
• Clamp-on power meters
• High-current measurement equipment

Using a current coil can significantly expand the effective current calibration range while maintaining a compact laboratory setup.

Automated Power Calibration

The Transmille 3310A is designed for both manual and automated calibration.

Computer control allows calibration points to be generated automatically.

In an automated procedure, software can control parameters such as:

• Voltage
• Current
• Frequency
• Phase
• Power factor

The resulting measurements can then be recorded and evaluated as part of a structured calibration procedure.

Automation is particularly valuable for repetitive calibration workloads.

ProCal Calibration Software

The Transmille 3310A can be integrated with Transmille ProCal calibration software.

ProCal is designed to automate calibration procedures and manage measurement results.

Combining the 3310A with ProCal can help:

• Reduce manual data entry
• Reduce transcription errors
• Standardize calibration procedures
• Improve repeatability
• Increase laboratory throughput
• Simplify result recording

This provides an efficient solution for laboratories regularly calibrating similar types of power measurement equipment.

Communication Interfaces

The Transmille 3310A provides communication interfaces for integration into computer-controlled calibration systems.

Available connectivity includes:

USB

RS232

and:

GPIB

These interfaces allow the calibrator to be incorporated into both modern and established laboratory automation environments.

GPIB is particularly useful for integration into existing automated calibration systems containing older laboratory instruments.

Laboratory Applications

Typical applications include calibration of:

• Power meters
• Wattmeters
• Power analyzers
• Clamp meters
• Electrical energy measuring equipment

Manufacturers of electrical measurement equipment can use a controlled power source for production testing and final verification.

Typical industries include:

• Electrical instrumentation
• Energy
• Manufacturing
• Aerospace
• Electronics
• Industrial maintenance
• Calibration services

The ability to automate calibration procedures also makes the instrument attractive for repetitive production and quality control applications.

Efficient Calibration Workflows

Using one dedicated power calibrator can simplify the laboratory setup compared with separate voltage sources, current sources and phase-control equipment.

The Transmille 3310A combines these functions into one coordinated platform.

This can reduce:

• Number of individual standards
• Connection changes
• Setup complexity
• Calibration time
• Risk of configuration errors

The result is a more efficient and repeatable power calibration process.
