SMC LET-2010-RD – Primary Injection Test equipment up to 13,000A.

• Primary Injection Test equipment up to 13,000A
• Control: manual
• 3-m / 10 ft. power supply cord
• Built-in digital ammeter, 0.5% accuracy (not included in the LET-400)
• Built-in digital timer, 1 ms resolution (not included in LET-400)

It allows to perform with sufficient power, all the primary current injections to test the proper function and wiring of all the elements that compose the protection and measuring section in a substation.

The regulation system is based on a continuously variable autotransformer (Variac) that supplies to a power transformer that delivers the high current outputs and isolate the main supply from the load. A built-in ammeter and a timer gives the information about the current value and the operation time of the relay or breaker under test.

APPLICATIONS

• Permanent current up to 2000A 6kVA in 3 Ranges.
• Made with two units.
• Built in digital ammeter 0.5% accuracy.
• Built in digital timer resolution 1 ms.
• Thermal and shortcircuit protection.
