Buried cables can, at any time, be subject to damage. Mechanical excavators are the most obvious but cables can also sustain damage from ‘moles’, trench-cutting machines, tunneling rodents, even from someone driving in a tent peg! Damage sustained may not cause the cable to fail immediately . – some cables have lasted a number of years after being damaged. Some cables may fail without having been damaged.

When a cable fails, someone, somewhere loses their electrical supply. We can provide a cable fault lo cation service that includes:

• Taking full control of electrical safety.
• Locatiing, pinpointing the position of the fault.
• Cable Fault Location.
• Cable Sheath Location.

Gases, vapours, mists and dusts can all form explosive atmospheres with air.
Hazardous area classification is used to identify places where, because of the potential for an explosive atmosphere, special precautions over sources of ignition are needed to prevent fires and explosions.

General Summary

PLC ensure intrinsically safe equipments remains in satisfactory condition for use within a hazardous area.

As it is critical to create either a continuous or periodic inspection interval. According to IEC 60079-17 [ed4.0], there are five different inspection methods that ensure the continued reliability of plant equipment:
– Initial
– visual
– close
-and continuous supervision.

While all but continuous supervision are periodic checks, continuous inspection requires your organization to frequently inspect, service, care for, maintain, and be trained on current and future hazardous area installations. Continuous inspection also does not remove the requirement for scheduled periodic inspections. By relying primarily on a periodic inspection approach, your organization will need to maintain a proactive schedule to ensure visual, close and detailed inspections are occurring at appropriate intervals, taking into account the installation application, equipment deterioration over time, and manufacturer’s guidance. The interval between detailed inspections should not exceed three years without seeking expert advice for fixed installation applications and one year for moveable (portable) equipment applications. Once the interval is determined, each installation should be subjected to additional interim sample visual or close inspections to support .PLC proposed detailed inspection interval. Setting the proper maintenance schedule for your intrinsically safe equipments helps promote a strong understanding of the condition of hazardous area equipment over its life. PLC ensures helps to ensure that you provide a safe environment for your processes, business and employees.
