Z-OVR Cable Impedance Test System750ADM & PCU1-SP Primary Current Injection System
3 voltage outputs & measures long line distancesDesigned for testing devices used for power system protection
Rail ApplicationRail Application
This unit is being used on rail catenary to ascertain the condition of the catenary using impedance measurement, over time the condition of the catenary will deteriorate and as that happens the impedance will rise.750ADM and the PCU1-SP are both Primary Injection Test sets, these are being used to determine that the CB and associated equipment will trip upon current fault conditions by injection of trip level current upon the protection system ensuring it operates as it should providing the protection as required.

These High Current Low Ohmmeters are used in the test and measurement of any current carrying conductor where low resistance needs to be assured – this includes the following applications: Cable Terminations, Hook Link Switches and Circuit Breaker Heads.  The DMO200 will supply 200A at 5V DC.  DMO200 has been used to measure the connection of the Track Hook Switches ensuing they have a good connection.  If the connection is NOT good, then there will be excess resistance and as a result will overheat; so it is imperative that the resistance is a low value and that’s where the DMO200 has proved to be invaluable.

The unit is attached across the Hook Switch Joint with the current initiated at a low Amp setting before slowly ramping up using the control knob.  This allows the engineer to see at what value it becomes stable.  This information together with the obtained resistance values allows for greater analysis (than just obtaining absolute resistance values).

The ability of slowly ramping up the current setting is a unique feature of the DMO200 (not included on other Low Ohm Meters).

The unit has the ability to output direct current the engineers to check trip settings on DC Current Breakers.  This aspect has recently been utilised by Network Rail engineers in the South East with the unit proving itself a trusted tester in an application where the electrification of the 3rd rail is 750V DC.


The 200ADM-P is a Secondary Injection Test Set with added features…

In addition to the main output (200A @ 10V AC) it has a second auxiliary channel (0-260V AC OR 0-10A AC), this means in addition to performing tests on current relays, the unit can also test relays where a second source of AC current or voltage is needed, such as current differential or directional relays.

In recent years the rail network’s electrical systems have been going through an upgrade and as a result more sophisticated relays are being utilised. A tester now needs to offer more than just current; whilst there are digital relay testers available, they offer limited power per channel (typically 30-50VA). These are designed for the modern digital relay and do not cater for older mechanical-operated relays… as these require extra power. The 200ADM-P is designed to output 2000VA from the main channel!

This unit has proven itself as an allrounder, able to test both single-phase digital and older electromechanical relays making it perfect for railway electrical engineering.


The PT30-10 is a 30KV DC Pressure Test Set used in the commissioning of cables; this unit is being widely utilised by rail-specialist, commissioning engineers who install cables. Upon cable installation cables need to be tested to ensure they have not suffered damaged during transit or installation. The unit is a DC test set offering 0 to ±30KV permitting two-core testing to either ground or to another core simultaneously. This allows for a more efficient commissioning process.
