  Porcelain Insulators: What are they?

  • An insulator is a material that resists the flow of electrical current.

  • In electrical transmission, an insulator is a component that ensures the current in electrical lines is isolated from physical support structures.

  • Porcelain is the oldest and most widely used material globally due to its physical properties. Alternates include polymer insulators and glass insulators.

Typical 3 pole High Voltage Disconnector

FUNCTIONALITY OF A DISCONNECTOR

Disconnect switches rapidly disconnect circuits from power supplies in the event of an emergency. Disconnect switches can function in conjunction with circuit breakers, devices which interrupt the flow of electricity along a circuit when the current exceeds the circuit's capacity.

Typical Current Transformer Configuration

FUNCTIONALITY OF A CURRENT/ POTENTIAL TRANSFORMER

A current/ potential transformer (CT/ PT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary.

Typical Surge Arrestor Configuration

FUNCTIONALITY OF A SURGE ARRESTER

A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.

A surge arrester works by diverting the extra voltage into the earth wire, rather than flowing through the electronic devices, while at the same time allowing the normal voltage to continue along its path. To protect a unit of equipment from transients occurring on an attached conductor, a surge arrester is connected to the conductor just before it enters the equipment.

RTV Coating Project: Porcelain Strengths meets hydrophobicity

• To avoid leakage currents, discharges and pollution flashovers, a highly customized silicone layer is applied to the porcelain insulator surface using either a patented dip coating process, or in certain cases a special spray coating process.

• This silicone layer provides an organically regenerative based hydrophobic surface that effectively combats the negative effects of contamination and enhances the electrical characteristics of the insulator

• The silicone layer also provides higher reliability of the insulator by overcoming potentially dangerous leakage currents on the surface of the insulator in highly polluted areas.
