.ERECTION AND OPERATION ELECTRICAL TEST EQUIPMENT 99
If other risks are likely occur during test and experiments, e.
The persons mentioned above shall ensure that all persons other that persons have left the
test area before the test equipment is:
- switched on, case voltages 1000 V
- made case voltages exceeding kV
In case test stations all persons must have leave the test area before the test station is
switched on. Test procedure
Assembly work and tests shall not performed simultaneously this could result in
danger.
In exceptional cases skilled persons may enter the test area the operational status ready to
switch operation. test laboratories, experimental stations and temporary test equipment with
voltages exceeding 1kV, switching operations may only performed upon the personal order of
the nominated person control the work activity, when he/she does not perform this duty
himself/herself.
In the event fault during tests, parts the test object and test equipment which are not
live during normal operation can subjected dangerous voltages.
In case test laboratories, experimental stations and temporary test equipment with voltages
exceeding kV, all persons must leave the test the test area before the test equipment made . exceptional cases,
work has carried out these parts, suitable insulating devices and auxiliary means shall be
used.
Work activities carried out the prohibition zone (live working) shall comply with the
requirements 50110-1. This
does not apply when endurance tests have left running the test equipment.Measures shall taken ensure that the prohibition zone not
reached.
The person carrying out the test shall able recognize the operational status any time,
especially when several voltages are supplied.g.
The nominated person control the work activity shall make sure that their instructions
are carried out correctly before the experiment:
- switched on, case voltages 1000V
- made ready switch case voltages exceeding kV
Orders for switching operations may only given nominated person control the
work activity.
Before leaving the test equipment, the out operation condition shall established.9.
11. noise, explosions,
radiations flying parts, gas formation, fire hazardous materials, additional safety measures
shall taken ensure adequate protection.
