In electrical work, especially in Gulf Countries substations, feeder pillars, and LV/MV cable work in UAE, a portable earth (temporary earthing) is used to protect workers from electric shock during maintenance and electrical shutdowns.
When an equipment it’s earthing system not good then used portable earthing #

1.
Permit and authorization
Obtain the approved permit to work, drawings, switching instructions, and authorization. Conduct a toolbox talk (TBT), job safety analysis (JSA), and LMRA.
Step 2.
Identify and isolate all sources
Confirm the exact feeder pillar, incoming supply, outgoing circuit, and cable identity. Isolate all relevant sources, including any alternate supply or possible backfeed, following the approved switching schedule.
Step 3.
Apply LOTO
Apply the required lockout/tagout, switching prohibition, and other controls. Verify isolation points and ensure nobody can re-energize the circuit while work is in progress.
Step 4.
Test for absence of voltage
An authorized person uses an approved, correctly rated voltage detector or tester. Prove the tester on a known live source, test the relevant conductors and phases against each other and earth as required by the procedure, then prove the tester again on a known source. Check all possible supplies and stored-energy hazards #

Cable Pulling Method

1. Before starting Method Statement Risk assessment

* Check approved shop drawing, cable schedule and route.
* Verify cable size, type, length and drum number.
* Inspect cable drum for damage.
* Confirm trench/duct/tray is completed and clean.
* Check ducts for blockage using a mandrel/brush and draw rope.
* Ensure required permits, toolbox talk and LMRA are completed.
* Establish an exclusion zone around the pulling operation.

2. Cable drum setup

* Place the drum on a suitable cable drum stand/jack.
* Drum must rotate freely.
* Position the drum so the cable comes off the top of the drum in the direction of pulling.
* Use a brake/control arrangement to prevent over-running.

3. Cable pulling
* Sand Bedding
* Sand Covering
* Warning Tape
* Warning tiles

* Install the approved pulling rope/wire and pulling eye/stocking.
* Use a cable pulling machine/winch where required.
* Do not exceed the manufacturer’s specified maximum pulling tension.
* Maintain the manufacturer’s minimum bending radius.
* Use approved rollers at changes of direction and along the route.
* For long pulls, provide adequate personnel to monitor the cable.
* Avoid dragging the cable directly on the ground, concrete or sharp edges.
* Maintain communication between the winch operator and cable-feeding team.

4. At bends and corners

* Install corner rollers/guide rollers.
* Ensure the cable does not kink or twist.
* Pay particular attention to the manufacturer’s minimum bending radius.
* Pull slowly at bends; do not use excessive force.

5. After pulling

* Leave the required cable length at both ends for termination.
* Arrange and secure cables properly.
* Identify/tag each cable.
* Seal unused ducts to prevent water, sand and debris entering.
* Inspect the cable sheath for damage.

Testing after pulling

Depending on the approved ITP/specification, typical LV cable checks include:

* Continuity test
* Insulation resistance (IR/Megger) test
* Phase identification
* Earth/continuity verification
* Sheath inspection
* Cable identification and termination checks # #

LIVE TERMINATION #

Confirm authorization
* Approved live-working procedure/method statement.
* Valid permit/LMRA or equivalent authorization as required by the project.
* Competent/authorized electrician and required supervision.
2. Identify the circuit
* Confirm feeder/cable, source, load and phase arrangement from approved drawings.
* Verify the correct DB/panel and cable using an approved voltage detector/test instrument.
3. Risk assessment
* Assess shock, arc-flash, short-circuit and accidental contact risks.
* Establish an exclusion zone and prevent unauthorized access.
* Remove unnecessary conductive materials and tools.
4. PPE
* Arc-rated clothing appropriate to the calculated arc-flash risk.
* Voltage-rated insulating gloves with appropriate leather protectors where required.
* Safety helmet/face protection and safety footwear suitable for the task.
* Use insulated tools rated for the system voltage.
5. Prepare the termination
* Keep exposed energized parts physically separated.
* Install the correct gland, lug, shroud/insulation and phase identification.
* Do not allow a tool or conductor to bridge phase-to-phase or phase-to-earth.
6. Termination
* Follow the manufacturer’s termination kit instructions and approved project specification.
* Maintain the specified clearances and bending radius.
* Torque lugs/terminals to the manufacturer’s specified torque using a calibrated torque wrench.
* Ensure PE/earth and neutral connections are correctly identified and installed.

#1. Planning & approval
* Obtain approved shutdown request/work permit.
* Confirm the exact feeder, cable, transformer, RMU/VCB, DB, etc.
* Review SLD and switching schedule.
* Conduct JHA/RA and Toolbox Talk (TBT).
* Notify all affected parties.
2. Identify the circuit
* Physically identify the correct equipment/cable.
* Cross-check equipment ID, feeder number, cable route and SLD.
* Never rely only on labels or drawings.
3. Isolate the supply
* Open the designated circuit breaker/VCB/RMU.
* Isolate all possible sources of supply.
* For systems with back-feed possibilities, check generators, UPS, solar/DG and other incomers.
4. Prevent re-energization
* Apply LOTO (Lock Out/Tag Out) as required.
* Put warning/danger tags.
* Keep the key under the authorized person’s control.
* Barricade the work area where required.
5. Prove dead
* Use an approved, calibrated voltage detector/tester.
* Test the tester → test all phases to phase and phase to earth → test the tester again.
* Confirm zero voltage before proceeding.
6. Discharge and earth
* Discharge stored electrical energy where applicable.
* Apply approved earthing/short-circuiting equipment according to the switching procedure and voltage level.
* For MV/HV work, only authorized/competent personnel should perform this operation.
7. Issue/confirm permit
* The authorized person confirms the isolation, dead condition and earthing.
* Work permit is issued/accepted before work starts.
8. Carry out the work
* Workers follow the approved method statement and permit conditions.
* Maintain required approach distances and PPE.
* Continuously control unauthorized access and possible re-energization.

Restoration after work

1. Complete the work and inspect the installation.
2. Remove tools, materials and temporary connections.
3. Confirm all personnel are clear.
4. Remove temporary earths as per the approved switching sequence.
5. Cancel/close the permit.
6. Remove LOTO only by the authorized person.
7. Energize according to the approved switching schedule.
8. Check voltage, phase sequence, indications, alarms and equipment condition.
9. Record the shutdown/restoration and inform affected parties #

-checking is necessary to ensure the correct electrical equipment/circuit is identified and isolated before shutdown, especially in MV/HV systems.

Key reasons:

* Safety: Prevents accidental isolation of the wrong circuit or equipment.
* Correct identification: Confirms the exact feeder, cable, RMU, transformer, or panel to be shut down.
* Avoids wrong isolation: Prevents shutting down an unintended live/operational circuit.
* Prevents back-feeding: Helps confirm all possible sources of supply are identified and isolated.
* Protection of equipment: Reduces the risk of damage caused by incorrect switching or energization.
* Continuity of supply: Ensures only the intended customers/equipment are affected.
* Compliance: Provides a controlled and documented isolation process according to the approved switching/permit procedure #
