Pro-Logic Technologies Limited is a multidisciplinary technical engineering company providing electronics, electrical engineering, instrumentation, automation, industrial control, electrical installation, equipment repair, maintenance and technical support services across Kenya.

Modern businesses, factories, commercial buildings, hospitals, schools, hotels, residential developments, institutions, farms, workshops, manufacturing plants and industrial facilities depend heavily on reliable electrical and electronic systems. Electricity powers production equipment, communication systems, refrigeration systems, pumps, motors, computers, security systems, elevators, lighting, heating systems, air-conditioning equipment and countless other technologies.

However, installing an electrical system is only one part of the engineering process.

A professional electrical and instrumentation solution must consider system design, load requirements, equipment selection, protection, control, measurement, commissioning, testing, maintenance, fault diagnosis, energy efficiency, safety and future expansion.

This is where Pro-Logic Technologies Limited provides a broader engineering approach.

Our work extends beyond basic wiring. We deal with electrical power systems, industrial control panels, electronic circuit boards, automation equipment, motors, drives, sensors, instrumentation, PLC systems, control systems, power backup, solar systems, electrical machinery, industrial electronics, telecommunications-related electrical systems, testing instruments and technical maintenance.

For electrical installation work in Kenya, regulatory compliance is particularly important. Kenya's Energy Act provides for electrical installation licensing and requires electrical installation work to be undertaken by duly authorized electrical contractors and workers. The Act also provides for testing, inspection and certification of installations.

Pro-Logic Technologies Limited approaches every project with this principle:

ENGINEERING SHOULD NOT ONLY MAKE EQUIPMENT WORK; IT SHOULD MAKE THE SYSTEM SAFE, RELIABLE, MAINTAINABLE AND FIT FOR PURPOSE.

In some cases, board-level repair is economical.

In other cases, replacement is the better engineering decision.


101. WHY PROFESSIONAL DIAGNOSIS SAVES MONEY

Uncontrolled component replacement can become expensive.

For example:

A machine stops.

A technician replaces the motor.

The machine still does not operate.

Then the VFD is replaced.

The machine still fails.

Then the PLC is suspected.

This approach wastes money.

A systematic diagnostic process starts with measurements.

The objective is:

FIND THE ROOT CAUSE BEFORE REPLACING THE COMPONENT.


102. ROOT-CAUSE ANALYSIS

Root-cause analysis asks:

Why did the component fail?

If a motor burned out, the investigation should not end at "motor failure."

Possible root causes include:

  • Overload
  • Phase imbalance
  • Undervoltage
  • Poor ventilation
  • Bearing failure
  • Incorrect motor sizing
  • Excessive starting
  • Incorrect protection
  • Mechanical blockage

Repairing the motor without correcting the cause can lead to another failure.


103. CUSTOMER-CENTERED ENGINEERING

Pro-Logic Technologies Limited focuses on understanding the customer's operational problem.

A customer may not simply need:

"An electrician."

They may actually need:

"Why does my production line stop every afternoon?"

Or:

IMPORTANT TECHNICAL DISCLAIMER

Electrical, industrial and instrumentation work must be carried out by appropriately qualified and authorized personnel and in accordance with applicable Kenyan laws, regulations, standards, manufacturer requirements and project specifications.

Kenya's Energy Act places requirements around authorized electrical contractors and workers, while EPRA publishes the applicable electricity regulatory framework.

Applicable Kenyan standards should be checked for the specific project because standards are periodically reviewed and updated. KEBS expressly advises users of standards to ensure they are implementing the latest applicable versions.
