  1. Monitor your transformer before it is <\/span>installed, for any burning smell, cracked <\/span>or unsuitable power cords or plugs and <\/span>loose or misaligned parts.<\/span><\/li>\n
  2. Regularly inspect your transformer to <\/span>minimise system failures or breakdowns.<\/span><\/li>\n
  3. When any work is performed on the <\/span>transformer, it should be done when the <\/span>equipment is de-energised, tagged out <\/span>and the circuit should be shut down.<\/span><\/li>\n
  4. Remain cautious of system overloading.<\/span><\/li>\n
  5. An individual working with transformers <\/span>should be using protection equipment <\/span>specifically rated for the transformer\u2019s <\/span>voltage output.<\/span><\/li>\n
  6. The overcurrent protection should be <\/span>maintained at the correct level as per <\/span>the equipment standards.<\/span><\/li>\n
  7. Always ensure that your transformer is <\/span>grounded. Transformer grounding <\/span>removes any static charge which would <\/span>otherwise accumulate.<\/span><\/li>\n
  8. Be sure to take note that power source <\/span>for control circuits will still be on even <\/span>after interlocks on equipment <\/span>disconnect.<\/span><\/li>\n
  9. Make sure no spare nuts, tools or any <\/span>foreign objects fall onto or into the <\/span>transformer.<\/span><\/li>\n<\/ol>\n

    \u00a0Regularly performing a range of standard tests has proven an effective way to gain reliable insight into the operating condition of your transformer and can extend its lifespan. Mechanical changes to winding, contact problems in tap changer or at other connections, shortened windings\/coils, as well as interruptions or short-circuits of parallel lines can all be diagnosed early by using conventional testing methods.<\/span><\/p>\n

    Capacitance and power factor\/dissipation factor (PF\/DF) measurements are performed to investigate the condition of the insulation of power transformers and bushings. Both insulation systems are essential for the reliable operation of the transformer.<\/span> <\/p>\n

    Frequency response analysis is a powerful, sensitive method for testing the mechanical integrity of transformer cores, windings and press frames, in power transformers. The test should be performed as a base line fingerprint at the factory which can then be used for comparison following installation, commissioning, maintenance and large disturbances.<\/span> <\/p>\n

    \u00a0Determining the moisture content within the dielectric insulation is a very important way for assessing the reliability and lifetime of a transformer. While conventional methods are very inexact, our test systems use the latest graphic visualisation software and standards to analyse the PCB, CO2\/CO, O2\/N2 and C2H2\/H2 levels with industry standards in an easy to interpret report.<\/span> <\/p>\n
