Commissioning
Methods
General Principles
1 Conduct all tests with the MV cubicle completely isolated and the MV circuit
breaker racked out (disconnected and open)
2 Perform all tests in the operating situation: no wiring or setting changes,
even temporary changes to facilitate testing, are allowed.
The SFT2841 parameter setting and operating software is the basic tool for Sepam™
users. It is especially useful during Sepam™ commissioning tests. The tests
described in this document are based on the systematic use of this tool. You can
perform the commissioning tests without the SFT2841 software for Sepam™ units
with advanced UMIs.
For each Sepam™:
b only carry out the checks suited to the hardware configuration and the
functions activated
b use the test sheet provided to record the results of the commissioning tests
A comprehensive description of all the tests is given later.
Checking Current and Voltage Input Connections
Factors affecting secondary injection tests include, but are not limited to:
b the type of current and voltage sensors connected to Sepam™ for residual
current and voltage measurement
b the type of injection generator used for the tests: three-phase or single-phase
generator
b the type of Sepam™
These tests check the current and voltage input connections. The descriptions below
also include:
b a detailed test procedure
b the connection diagram of the associated test generator
Determining Checks to Conduct
The table below indicates the page on which the following are described:
b general tests performed according to the type of measurement sensors and
type of generator used
b additional tests performed for certain types of Sepam™ having a single or
three-phase generator
