To secondary inject an ADIT relay, you typically connect a variable AC or DC power source to the relay's input terminals while ensuring that the relay is isolated from the system. Use appropriate test equipment to apply the desired voltage or current levels, simulating the operating conditions. Monitor the relay's response to verify correct operation, ensuring safety protocols are followed throughout the process to prevent damage or injury. Always refer to the specific relay's testing guidelines for accurate procedures.
Adit means " walks beside him"
An adit is a horizontal access shaft to an underground mine.

Normally the Over current relay is connected using a suitable CT (Current Transformer). Say the CT ratio is 100/5 Amps. (secondary is normally 5 or 1 amps). 100 Amps in the primary induces 5 amps in secondary which flows through over current relay circuit. Secondary current is proportional to the primary current. To test the OCR , inject the current into relay circuit ranging from 0 to 5 amps in steps (which represents upto full load current on primary). Relay will operate accordingly operate the trip contacts. These relays are normally with a time factor setting as well.
It's an ADIT
A horizontal entrance to a mine is known as an adit.
IF answer is yes . please explain how we can measure in primary side ??
use secondary injection test with pilots connected.
YES
a dude
the ref relay rct secondary output how much current
adit
