As a part of one of the world’s leading manufacturers of Power Resistor products, Fortress Systems utilises the groups corporate resources and facilities for product design and testing.

TEST FACILITIES

We have calibrated test equipment for all routine testing, including resistance meters and insulation testers, temperature gauges and a 50kV dielectric tester.

The Group testing facilities we have available include a 1.85MW dc power source, a 400kV impulse test generator, shock and vibration test facilities, and FEA analysis software.

This is used both for in-house development and for routine and type-testing customers’ equipment.

CONTROLLED POWER SUPPLY

A 1.5kV chopper-controlled DC power source, continuously rated at 1.5MW, enables us to test resistors at full load power and under simulated cyclic conditions.

IMPULSE TEST TO 400kV

We have a 400kV impulse generator that can be used for dielectric and through impulse tests of high voltage resistors

VIBRATION TEST FACILITIES

The equipment consists of two vibration tables (one with a vertical axis and a second one with a horizontal axis) equipped with hydraulic cylinders 16000 daN allowing the execution of vibration, shock and seismic tests on devices up to 2000 kg. Potential tests include dynamic strength tests, long life tests, noise levels and road simulations. In addition to the tests we carry out, we also have the capability to carry out static and dynamic finite element analysis of our equipment.

COMPUTERISED DATA LOGGING

The test laboratory is equipped with computer-controlled 32 channel data logging equipment and optically-isolated transducers for high voltage measurement and recording. Test variables such as temperature, power and current are also recorded.
