Lightning Impedance Tester: Model 4051

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.

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.

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.

Testing of Closed Links

MSVT 20

For the testing of multiple single-phase meters with fixed links between the voltage and current path on a test bench galvanic isolation must be provided at each test position. This can be done with isolation transformers for the voltage path or the current path at each position.

Meter Test Systems

Multi Position Test Systems

The individual system components of a MTE meter test system are modularly developed and can be combined in any order for testing of single- and three-phase meters with or without closed I-P links. Test systems are available with fixed meter racks or with moveable trolleys and gantries to fulfill different requirements and increased test capacity.

Phase Angle Meter: Model 597C

A precision phase angle meter in 50Hz or 60Hz version, the 597C has been in production for well over 10 years. It has inputs for voltage, direct current or current via a clipon CT.

Watt and Phase Angle Meter: Model 632A

We have sold many of these simple, accurate and robust instruments to utilities, industry and educational institutions. They are used for many purposes, from student instruction in the electrical laboratory to quality control in appliance testing.

Phasor Meter: Model 633

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.
