Yesterday was the 1st time ever that I take charged for switching off bay in order to carry out works in the switchyard. Luckily everything went smoothly.
This time, we had requested outage for a 132/33kV transformer bay in order to replace the Neutral Earthing Resistor (NER) by the contractor. The work started at 7:00 am and completed at 4:00pm.
So as an Authorised Person in charged, I have to make sure that all safety precaution for the works are in place. So, after the switching whereby the Tx bay was off, isolated, I have to make sure that it was discharged and earthed and remain dead during the entire work. Portable Earthing were installed at both HV and LV side of the transformer.
Confirmed that the bay is safe for working, I gave safety briefing to the workers. Informed them on the coverage of area that was safe for work and are that is Live an dangerous. I also ensure that all workers were wearing Personal Protective Equipment (PPE) such as safety helmet and safet shoes.
