CT | PT Testers
Following feedback from our users, our Model 590G-V3 is the latest version of this successful and well proven CT error tester. The 590G-V3 has all the features and advantages of the previous models with additional testing features, better accuracy and smaller size and weight.
CT | PT Testers
This full featured product combines all of the metering CT test abilities of the popular 590G-V2 model with the additional advantage of also being able to perform both protection CT excitation tests as well as burden based inductive PT tests.
Energy Meters
The Model 689B meter tester uses a Digital Signal Processor and a display processor to measure and calculate meter errors to 0.03% or 0.1% accuracy.
Earth | Ground Systems Testing
Portable current injection system designed to simulate system fault currents and their effects on electrical and utility infrastructure

The Model 4062 is a frequency adjustable switch mode current injection source that is in effect the bigger brother to the 200 VA injection unit above. It is used to drive variable voltage and current magnitudes into an earthed or passive load loop at maximum power continuously if required.

The 4063 is an 1800 VA rated coupling transformer with eight individual tap settings covering an impedance range from 1 to 200 Ohms. Used in conjunction with the Model 4062 the tap selection must also be reflected in the tap menu settings of the Injection Unit which also drives the coupling transformer.
Phantom Loads | Installation Instruments
This 3 phase phantom load is used for energising either CT or Direct connected Energy meters during commissioning or routine testing.

3 Phase, 4 wire 240V / 415V 50Hz + Earth 3 phase 10A circuit breaker used to protect the unit. Neon indicators indicate which phase is live Output configuration is switchable from star to delta.
Phantom Loads | Installation Instruments
Simple and easy to use, this 3 phase load is used in pre or post commissioning of metering and / or measurement products. Easy way to determine correct installation and phasing of equipment.

The Model 4041 is the largest of our switch mode current injection sources used for injection based testing. This 3 phase unit works on the identical principle of operation as our 2kVA system, however the 4041 in conjunction with the 4042 coupling transformer have been specifically designed to perform current injection tasks over very long haul and demanding environments continuously at maximum power.

Model 4042 is our largest coupling transformer, with eight secondary taps rated to 8kVA. The 8 taps on the 4042 allows the user to adjust the injection voltage and current to a desired value via individual tap settings whose impedance ranges from 1 to 80 Ohms.

When performing earthing/grounding system tests it is essential to filter out the predominant 50 or 60Hz currents that are often present in a typical test situation. This is done by injecting at frequencies other than 50 or 60Hz and making sure that the instrument which detects voltages and currents around the loop is tightly tuned to the same frequency.
