SYSTEM DETAILS
SYSTEM CHECK
The instruments are line operated
2
. The systems are designed to be used with AC Voltage power
sources between 90 to 264VAC 47…63Hz. The systems perform a self-check each time that they are
powered on. The User should always visually inspect all connectors, cables and devices to be
measured to avoid any safety issues.
LIMITATIONS OF WINDING RESISTANCE TESTING
In general, there are no limitations on testing low or high inductive windings of transformers.
The test systems are specially designed to test all transformer windings.
