20. Primary & Secondary Current Injection Test
MCCB/ACB
• Test relay protection systems and their current transformers together.
• Current level maintained though test circuit resistance may rise due to
heating.
• Built-in timer to record protection relay operation.
• This Primary Current Injection Test Set is rugged, self-contained and designed
for operation by one person, due to its portability.
• The test set has a separate hand-held controller connected by an
expandable cable. This allows the operator to work close to a protective
relay while controlling a test. The maximum output current is 5000A - AC at
line frequency. By changing the range switch, half the rated output can be
obtained at twice the voltage.
• Additionally, a separate auxiliary voltage output of 300 V, 2 A - AC or 125 V,
2 A - AC is available for testing voltage operated relay coils or checking the
magnetization characteristics of current transformers. All outputs are fully
variable and each test set has a nominal duty cycle when delivering full
current and voltage. Continuous operation is possible at 40% of maximum
current.
