CT | PT Testers
Ability to test for ratio errors at up to 500VA burden. Selectable Power Factor. Ratio error accuracy to 0.05%. Four selectable CVT test point standards to choose from. Tests CVT rated to 500kV with up to 3 secondary windings. Truly portable ~ 20kg.
Earth | Ground Systems Testing
The 4025E is the latest revision in our 4025 series of frequency selective multi-meters. It maintains all of the features of the previous models for measuring the I/V magnitudes and phase of signals induced into an earth loop via high power current injection.
Earth | Ground Systems Testing
The ECT-4 is a 4 wire Kelvin micro-ohm meter used to check the electrical quality of metallic structures and their connection integrity to other bonded structures in grids and electrical systems such as a sub-station or transmission station.
Earth | Ground Systems Testing
The 4051 lightning impulse impedance tester is used to inject a simulated lightning impulse signal at up to 30 Amps between two electrodes such as a Pylon footing and a remote test electrode.
CT | PT Testers
In high revenue areas such as universities, shopping malls and business centres, taking CT's offline for testing is not an option, so a reliable live CT test alternative is required.
CT | PT Testers
The model 595LV is designed to test the translational integrity of Low Voltage* metering CTs which are permanently commissioned and cannot be taken offline. The 595 LV also allows the user to actively measure a metering CT's admittance and secondary burden. When combined with the measured current error, the 595 LV satisfies the majority of the minimum testing requirements of a Live metering CT installation.

The model 595HV has been developed to work as an isolated high voltage primary current extension to the 595LV above. The 595HV wirelessly connects to the 595LV and the two synchronously measure and sample a HV CT's current and phase error accurately to within 0.1% of manufacturer's specification.

The reference Transformer comes in a rugged pelican case with with terminal posts for connection and selectable transformer tap switches which allow the operator to calibrate a 590 series CT tester over a wide range of ratio settings.

This complements the Model 632A, since the Model 633 reads phase angle, true rms voltage and true rms current in a circuit. This instrument is designed to demonstrate the properties of phasors and real/imaginary number notation for electrical engineering students.

The Model 4014 integrates four ammeters for the direct and simultaneous reading of 4 CT secondaries up to 10A during the setting up or checking of protection systems while they are in service with normal 50/60Hz primary currents flowing.
