ProTesT
ProTesT is a software system for protective relay testing and equipment
maintenance. It includes the F6000 Control Panel for manual control of
the instrument. It also combines automatic control of the
F6000 Instrument with the functions of a client server database.
ProTesT uses test templates called macros to automate tests on protection
scheme relays. The ProTesT database also documents relay settings, test
conditions, and test history. Figure 1.3 on page 1-4 illustrates how the
ProTesT software interacts with the F6000 and with the relay under test.
ProTesT allows the use of three testing methods:
• Steady state relay calibration
• Dynamic state testing
• Transient testing
Steady state relay calibration uses macros to automate tests on protection
relays and schemes. These macros test individual relay functions, such as
reach, instantaneous overcurrent, reverse current response, pick up and
dropout, and operation and reset timing.
Dynamic state testing uses a special state simulation macro. The state
simulation macro simultaneously applies fundamental frequency
components of voltage and current that represent power system states.
Typically these states are pre-fault, fault, and post-fault.
Transient testing uses the optional ProTesT TPlan. Transient simulation
tests simultaneously apply fundamental and non-fundamental frequency
components of voltage and current that represent power system
conditions obtained from Disturbance Fault Recorders (DFR) or system
modeling tools such as EMTP or ATP. The DFR and system modeling tool
data are typically stored in a COMTRADE file. ProTesT TPlan can work
with COMTRADE files.
To enhance the capabilities of the F6000 Instrument, ProTesT:
• Automates protective relay tests to reduce testing time and
increase accuracy
• Tests complete protection schemes under realistic power system
conditions
• Creates standardized test plans with repeatable results
• Stores test plans and test results for later retrieval and analysis
