Overseas HV Networks

Stating the Obvious

• Around the world utility and electricity network operators are legally

required to design, build, operate and maintain their electrical systems in

a manner that reduces the risk of injury or death to people whether they

are at work or members of the general public. Generally the legislation

also imposes a duty on employees, including contractors, to work in a

safe manner.

• They are also generally required to manage their electrical assets using

recognised good practice techniques to ensure:

1. Good supply quality;

2. Continuity of supply.

3. Safety;

4. Effective use of capital and repair and maintenance costs;

The consequences of failure can be catastrophic

Substations in Disguise

You would never believe it

UFO reported in Puerto Rico

This photo shows an alleged visitation by a UFO on the evening

It was reported that the immense circular UFO hovered motionless in mid-air radiating an intense amount of light onto the

substation, oh dear me!

Just couldn’t resist it
