As panel builders, electrical engineers, technicians, students or designers, you are led to work on MV electrical installations. These require equipments as well as a specific technical setting up to be efficient.

The setting up and the standards evolves together and to be up to date with the procedure to follow is becoming difficult. Furthermore, the quality of such an installation depends on several factors which have their own importance. Because of this, you sometimes encounter difficulties to summarize this technical information and it becomes hard for you to put them into practice during your daily interventions.

The consequences on your efficiency in the field are immediate: you lose time making researches to be up to date; you propose installations that you master only to your clients, and these are not conform to standards which also means non-optimized nor safe.

Stop enduring this situation! Just for you, we’ve searched and gone through several free technical guides available online. Further to our investigation, we’ve selected the best 3 and we’ve awarded them a gold, silver and bronze medal.

Electrical Installation Guide 2015

Designer, Consultant, Contractor, Panel builder, Facility manager, Student, teacher, Standardisation or certification experts… we all have to know and comply to electrical installation standards and regulations, in order to ensure the safety (and more and more the energy efficiency) of our customers’ electrical installations.

These international standards, set by the IEC, are complex and keep evolving; as a result, we struggled to stay informed.

As an example, are you aware that the IEC 60364 “Low-voltage electrical installations” part 4-42 “Protection for safety – Protection against thermal effects” has been updated in 2014, and that in particular it now includes recommendations for arc fault protection?

Introduction

In the preceding article we studied the basics of Earthing and also the basic most Earthing type where the neutral is grounded at source and optionally grounding is done even at customer side.

Besides this, International Standard – IEC 60364 formally defines different types of Earthing arrangements. Let us examine them here in detail.

Earthing system design

Electrical protection and lightning protection

I have a query on earthing system design. One designer has submitted me an earthing plan which interconnects the earth electrodes meant for equipment earthing and those for lightning protection purposes. By combining the earth electrodes he achieves overall earth resistance below one ohm required by IS 3043 (Indian standard).  But my question is whether this is an acceptable practice followed by industry or the earth electrodes of the two systems (protective earthing and lightning protection) can not be combined this way?
Would appreciate feedback. thanks in advance.
