Note
This instruction of test is developed to be conduct with Rigel 288 Safety Analyzer. Using another Safety Analyzer model may require some adaptations.
Prerequisites
Before performing this protocol, record the serial number, calibration due date for all calibrated equipment and other required data in the test datasheet
IT0738A.
6.0 Test Conditions
The tests may be performed at the ambient temperature, humidity, atmospheric pressure and mains voltage as present at the site of testing.
7.0 Normalization Instructions
As this test is performed at actual mains voltage present at the site of testing, measurement result have to be normalized before comparing with
acceptance criteria. The normalization will be done according the formula:
Equipment Leakage Current =
8.0 Earthing System
Retrieve information related to the earthing system (grounding system) of the electricity supply systems of the location where the test will be
conducted. It could be TN-System or IT-System. IT-System is commonly found in Operating Room environment and TN-System is mainly found in
workshop or biomedical workshop environment.
Depend on the earthing system, different measuring methods will be applicable for leakage currents measurements and will be described in the
following paragraphs.
The Rigel 288 informs the user when the test is performed under IT-System network by the following message.
