 Testing Electrical Installations. March 7, 2008

A good and well laid out book with clear diagrams. This is an ideal book for students when they begin to do their dead and live testing. Note on review below re. measuring Ze, GN3 and the NICEIC do state disconnecting the means of earthing from the installation earthed equipotential bonding to remove parallel paths.

I bought this book because I am in my second year of Studying City & Guilds Electrical Installation 2330; attend two evening classes per week. This course consists of underpinning knowledge facilitating entry into a career as an Electrician, although I work full time in a completely different industry. I have found the book useful because the clear diagrams and attendant explanations can be used to back up testing and inspection on our practical work and during class discussions. I have recommended this book to my fellow students some of whom are electricians working to gain qualifications; they have found the information very useful.

I think this is an excellent publication. I take on board the comments about testing for Zs and I agree with the author of the book. I have come across installations where there is no actual true Ze, but it is being provided by other parallel earth paths. Testing this way is about risk assesment and there is a big difference between testing domestic and industrial properties. At least this author has had the courage to pragmatically show testing and the efficient and accurate ways to do it. Too many people think they know how to do it, but have never actually tried to do it. If they had they would understand the confusing results that you get with the effect of the parallel earth path problem - difficult to explain when the sums just do not add up!
My only criticism of the book is that it would have been nice to have had the Zs table and the protective devices table and fault current graphs included out of the regs. It would just reinforce why we are testing and what we are truly looking for.
But an essential for those sparks who need a refresher and don't want long winded explantions and an absolute must for any young sparks starting out, I wish I had this 30 years ago.

This book has good clear diagrams which show you exactly how to carry out testing. This is complemented by clear, easy to understand explanations of what to do and when to do it. In my opinion this is a must have book, always useful when on a job to use as a quick reference guide, I must stress the diagrams are very clear and easy to understand and the explanations down to earth and very understandable.

with reference to comments left by 'a reader' Below i would like to point out that for an acurrate measurement of ZS it is perfectly obvious you would indeed need to remove all 'Parrallel Earth Paths' from the equation.
It is without doubt a procedure which should be carried out under the safest cucumstances
i.e ( all persons and livestock NOT to be present during the test duration)
i feel your comments for saying this book is not relied upon to be completely irrational and totaly un-justifiable.
Testing and inspection nowadays is only carried out by competent personel and such personel would have the ability and knowledge to realise that this process of reading ZS is entirely required and should be carried out in a manner that would involve zero risk.
I think 'A reader' will now need to re-test every job he/she has ever tested as all of his/her ZS readings are most definitely inacurate.
this book is one of the best ever written on the subject in my oppinion.
keep up the good work trevor marks!!
