PHASE FAILURE RELAYS Three-phase equipment, more so motors, must be connected to the rated nominal voltage for them to function well. If there is any loss/disconnection in any of these phases, then the motor will continue operating with the remaining two. This phenomenon is called phase failure or single phasing. When single phasing occurs, the motor continues to operate at reduced speed and experiences vibrations. Moreover, the line current also increases appreciably in the remaining phases. This increase in current...

The Industrial Power Gem. The consequences of poor power quality are far-reaching; these may include unscheduled downtime, low equipment life, reduced productivity, and penalties that have a significant financial impact on the end-user. However, the equalizer technology from Power controls by Elspec which is the world’s fastest real-time power quality enhancement system optimizes all power quality factors and more, for a variety of dynamic fast-changing balanced, unbalanced & single-phase loads. The equalizer features electronic switching of 5-20 Milliseconds @ 50...

The introduction of smart meters by KPLC has brought forth unprecedented problems to electricity consumers, especially those with large inductive loads. Most of the available old range of pf controllers in the market are not fast switching and also tend to use one CT as opposed to the new range of pf controllers that use three current transformers. The efficiency and accuracy of an automatic power factor correction bank in correcting the low power factor is subject to the quality...

Low voltage panels are integral components of the electrical distribution system. These panels are essential for branching electrical circuits. The main component of the LV panel is the switchgear. Switchgear comprises electrical disconnections that are essential for the control, isolation, and protection of electrical equipment. They include fuses, circuit breakers, contactors, Earth Leakage Circuit Breakers (ELCBs), and relays.  Power controls Ltd is an industry leader in the design, manufacture, assembly, as well as importation of; quality,well-engineered, and cosmetically appealing LV...
