NPG Unit 662 Power Distribution - Plant & Apparatus

Geothermal generators produce energy from

• heat of the earths core

• heat of the sun

• wind

• waves

The Office of Gas & Electricity market regulates

• power generation , transmission and distribution

• Plyons

• overhead cables

• ISO standards

The protection of consumers interests is

• the responsibility of COSSH

• the responsibility of RIDDOR

• the responsibility of the UK Electricity Regulator

The reduction of electrical losses in the lines can be attributed to

• High Current Transmission

• High Voltage Transmission

• The standard design of plant equipment

• Maintaining statutory distribution voltages

132kV to 33kV 33kV to 11kV 11kV to 400kV is the three step-down stages for

• Small Towns

• Industrial Estates

• Factories

• Homes

Reducing the transmission voltage is the primary purpose of a

• step-up transformer

• generator

• step-down transformer

an explusion cartridge fuse is used

• In the protection of high voltage circuits

• in a domestic plug

• in the protection of low voltage circuits

discrimination in a circuit refers to

• multiple protection device circuit - fault trips closest device

• multiple protection device circuit - fault trips furthest device

• multiple protection device circuit - fault trips all devices

• multiple protection device circuit - fault trips no devices

double wound transformer has a turns ratio of 12:1. If the primary voltage is

360 V, the secondary voltage will be

• 30V

• 60V

• 90V

• 1200V

increases or decreases in output voltage ar atrributed to

• fuses

• cables

• lights

• Transformer tap changers
