also disadvantages. The human being is a user of
electrical energy, but, unfortunately, does not
have any sense organs to perceive it and did not
form any natural reflexes to protect itself against
the possible hazards of electrical energy.

By forming and using its knowledge, adapting
its behaviour and by using the right equipment,
it must compensate for this evolutionary deficit.

Live Working
Nowadays, with international competition, permanent
availability of electrical energy has become an important
factor. At the same time, the increasing competition on
the power supply market prompts the facilities to reduce
more and more their provisions of excess capacities of

power supply. Firstly, this requires an increased operational
safety of existing systems. Secondly, some parts of the

system cannot be disonnected completely during the
required maintenance and repair procedures.
For these purposes, live working is a good solution.
Basically, the following methods can be applied:
I Hot Stick Working Safe Clearance Working

I Insulating Glove Working Rubber Glove Working
I Bare Hand Working
TFRS MS Combined Cleaning Set
Because of the high skill requirements of live working,
this kind of work may only be done by qualified elec-
tricians or professionally instructed persons.
The advantages of this working method are obvious:
I Increased reliability of power supply
I Uninterrupted power supply for the customer.
Better rating of your industrial customers.

European standards provide a safety-related equalisation
of dead working and live working.
With the brand DELTEC®, DEHN + SÖHNE offers a wide
range of devices and equipment for this working method.
