Sasol/NATREF/Anglo American/SAPS

Sasol, the world’s first and largest oil-from-coal refinery in South Africa, broke ground in

creating the technology to covert low-grade coal into synthetic fuels and chemicals. It began in

1927 but has grown so large that coal is now responsible for 40 percent of South Africa’s fuel

Largest coal liquefaction (CTL) plant in the world

Radio Communications Uptime

Mission Critical Communications Systems require a high availability of service specified as 99.999%

This means that the downtime is less than 5.26

minutes per year.

To achieve 99.999% service availability: add site

redundancy and equipment to the network design

(backup sites, microwave ring network, equipment

redundancy, more antennas).

Redundancy comes at high cost

STOPPING LIGHTNINGS IS NOT

THE SAME ASPREVENTING IT FROM STRIKING

It’s better to stop something happening in the first place than to repair the damage

after it has happened.

Prevention is better than cure

19

Principle of a “bullet” (cartridge)

A modern centrefire cartridge consisting of the following:

1. bullet, as the projectile; 2. metallic case, which holds all parts together; 3. propellant, for example gunpowder or cordite;4. rim, which provides the extractor on the firearm a place to grip the case to remove it from the chamber once fired; 5. primer, which ignites the propellant

Remove the primer (5), and the bullet has no impact.

20

To protect a structure from lightning we need to remove the Igniter of the lighting (like the primer in the cartridge)

The DDCE operating principle is based on constantly

balancing the surrounding electric field, eliminating the

possibility of an ASCENDING STREAMER being

produced within its radius of coverage and thus

PREVENTING THE LIGHTNING FROM FORMING.

Separate positive and negative charges are produced inside clouds (electric field).

The DDCE unit compensates for variations in the

electric field, shunting them to earth in the form of

small leaky currents to re-balance the field.

This prevents the creation of the charge accumulation

and saturation of the electric field and an ascending

streamer, PREVENTING LIGHTNING FROM

BUILDING UP within the protected area.

Unsafe working condition (Nov 2018)

A telecommunications tower is located at 1.5 km from a cranes at a harbour in Japan (Nagoya United Container Terminal).The cranes accumulated high voltages that present a safety hazard for people.

Measurements have been taken on site.

The voltage values in the peak are over 1200 V, the current values are between 5.31mA and 39.22mA. These values are over the safe limit for humans.

23

It is proven by measurement that after the installation of four DDCE’s the voltage values, and therefore the current values, are much lower and within international safety values

DDCE Protection Zone & Product Warrantee

5 year equipment warranty

Free manufacturer insurance cover for electronic damage (installed by ESS accredited agent)

Possibility of reducing insurance cost of current policy

25

DDCE Protection Zone

The radius of coverage will be 100 m, provided that

the DDCE has been placed at a minimum height of

26.79 m with respect to earth and that there are no

structures of the same or greater height within its

100 m radius of coverage.

It is also necessary to ensure that all existing

structures (metallic and/or conductive parts) within

this 100 m radius of coverage are at the same

potential, i.e., that they form an equipotential

system.

PT XL AIXATATBK

DDCE have proven to be successful and PT XL AIXATA is in the process installing DDCE on all problem sites

34% OF PT XL AIXATA TOWERS SUFFER DIRECT STRIKES

3 different Tower Protection systems have been used.

248 towers have been fitted with DDCE units

540 sites have been fitted with conventional lightning protection systems

Over a period of 2 years after the installations:

Direct strikes with DDCE: zero % with zero % break downs

Direct strikes with conventional lightning protection systems: 12.5% with 45% breakdowns

Scottish Power Offshore Wind Farm

The latest mega wind farm project in the United Kingdomconsists of the largest offshore wind farm in the world,with an installed capacity of 714 MW, which will supplyclean energy to more than 630,000 English homes.The offshore substation platform has been protected withthe Dinnteco DDCE system, protecting personnel andequipment against lightning

40

Scottish Power Offshore Wind Farm

The protection design and installation of the DDCE was carried out according and complying with the international standards IEC 62305 IEC 50164 and DNV-GL.

Offshore structures are considered high risk due to their isolated position in the middle of the sea and are prone to high level of lightning strikes.

Any lightning damage on offshore platforms can cause downtime in the supply of renewable energy. Repair at remote offshore platforms can be timeously and therefore can create loss of income and high cost of repair (accessible by boat of helicopter and depending on weather conditions)

Repairing and maintenance costs for offshore platforms make the Dinnteco DDCE technology especially suitable, reducing costs and converting corrective actions into preventive ones.

By illuminating direct lightning strikes, workers, mechanical structures, electrical installations and electronic equipment are protected.
