CHK PQ has developed partnerships with railways companies to design and develop new products, e.g. fast transfer switches and point condition monitors.
The transfer switches serve to switch supply from one source (e.g. normal supply) to another (e.g. stand by) very rapidly, thereby ensuring continued operation of sensitive downstream equipment (e.g. signalling equipment), without the need for uninterruptible power supplies (UPS) back up systems. This results in reduction of capital and operating costs.
The Point Condition Monitor is a self-learning device which determines normal and abnormal point operations and alerts users (e.g. via email) to potential faults, which can then be resolved before actual failure, thereby avoiding disruption to train services, expensive repairs and maintains the goodwill of train riders.
