Best Practices in Operation and Maintenance of Distribution
A power distribution substation is the heart of an electrical distribution network. Its prime objective is to step down power at the 66 or 33 kV level and distribute it in an 11 kV subdistribution network. ... For extra-high voltage above 300 kV, connection fittings are intended to reduce corona which may be a source of electromagnetic ...

Voltage Optimisers: How Do They Work & Are They Worth It?
Voltage optimisation technology could yield average energy savings of up to 15%. While savings begin immediately, payback is usually achieved after two to four years. A four-bed home, with an Eco-Max Optimiser, can see a …
Achieving (and maintaining) electrical connection tightness
problems observed in the first round were still present. Some had gotten worse. Examination of the repair records showed that when sus-pect connections were taken apart, cleaned, and put back together, 92% of them exhibited acceptable temperature. But when a
Complete Guide to Oil-Filled Transformer Maintenance
Do a comparison of the load voltage and current with that of the rated voltage. Keeping the overcurrent, differential, and ground current relays in a good condition will prevent electrical failure. The next thing to check is the Noise level. If your oil-filled transformer operates loudly, then it is important to know the reason for the noise.
