PPE Technologies - Integrated Electrical Engineering Solutions for Mining

Power Plant Electrical Technologies (PPE Technologies) provides integrated electrical engineering services, focused on supplying high technology systems and solutions, to the mining industry. The company exclusively works in sub-Saharan Africa, including all southern and central African Countries, and selected west African Countries

Electrical installation and fitment, on-site maintenance and turnkey project services

PPE has several business divisions including an engineering department for electrical and instrumentation design and commissioning services, an installation services department for on-site maintenance works and installation works, a project department for providing turnkey project services on an EPC and EMCM basis, and an electrical fitment shop facility providing motor control centres, power distribution boards, PLC and DCS panels, and a wide range of electrical and instrumentation solutions.

Earthing, lightning and surge protection for mine sites

PPE provides earthing, lightning and surge protection investigations for mine sites. We identify lightning protection zones using risk assessments and soil resistivity (Wenner method). We can then design and install earth electrodes, earth networks, equipotentialisation of earthing networks, and install surge, transient and lightning protection equipment.

Electrical reticulation and substation protection systems

We provide audits, testing, settings and grading for electrical reticulation and substation protection systems. These include the following:

• Injection testing on relays, one and three-phase secondary injection testing
• Assessment of existing relays settings and rectifications
• Engineering solutions on challenging relay setup, marshalling and application
• Full reticulation assessments and designs
• Testing of PFC units and independent capacitors
• Testing of CT and VT units
• Circuit breaker / contactor resistance tests
• Circuit breaker open / close speed tests
• Extensive knowledge on all well-known protection relays

EPC and EPCM for turnkey project

Construction contracting trends have been leaning towards the EPCM style of contracting and away from the EPC contracting for several reasons, but both have their place in business today.

Our engineering, procurement and construction (EPC) services include:

• One-stop shopping (one point of contact)
• Hands-off approach to project
• Minimal staffing requirements
• Minimal legal risk
• Best for well-defined projects
• Detailed engineering before contractor selected
• Minimal unknowns

Our engineering, procurement and construction management (EPCM) services include:

• Lower overall costs
• Staff's sense of ownership
• More control over process
• Better for less defined projects
• Normally anticipated changes to scope of supply
• Less legal litigation
• issues identified early
• Situation resolved before it becomes a larger problem
• Owners financing flexibility

Electrical and instrumentation installation

Our installation services department provides a comprehensive on-site construction and installation solution, from small retrofits and modifications to existing installations, to entirely new plants. Our installation teams are geared for operating in heavy industrial environment working for corporate groups, with high expectations in safety, quality and service.

To ensure a consistent quality of performance our site supervisor performance is built on four key pillars of management, namely the planning, leading, organisation and control of site works and site teams. Through clearly defining the scope of services required and having the implementation strategy for each installation, we ensure that the site teams and their supporting managers are focused on the same mission, with common goals and objectives for every undertaking.

We focus on planning, leading, organising and controlling our site works and ensure that key performance is clearly mapped to achieve end user satisfaction.

Power distribution load centres, motor control centres and control system solutions

The PPE Technologies panel fitment centre is geared for power distribution equipment up to 4,000A. Our service is geared to the manufacture of electrical, control and instrumentation control panels and enclosure to your requirement.

This includes on-site panel modifications achieved with the use of a portable bus bar press system in skilled and experienced hands.
