Short circuit and internal overpressure relief tests

Introduction

The Short circuit and internal overpressure relief tests are performed by the High Power Laboratory (AP2), located in the Adrianópolis Unit. They assess the behavior of lightning arresters when submitted to short circuits.



They are performed to assure that a failure in a lightning arrester won't result in an explosion. Thus, a greater safety for equipment and people around them are guaranteed in such events.



This kind of test is suitable for high voltage equipment. To this end, AP2 has the infrastructure to provide voltages and currents and meet the specificities of the clients and/or the test standards, within the limitations of the laboratory, for example: calibrated measurement systems; switches and circuit-breakers for current establishment and interruption; current limiters; protection systems; suitable current and voltage sources.

 

The main clients of these tests are: electricity utilities and equipment manufacturers.

 

Standardization

 

• IEC 60099-1
