  • Neutral point location of relay protection

    Neutral point location of relay protection

    The “star point” (or neutral point) is the junction where one end of each CT secondary winding is connected together. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. This can easily ientation can be either way without effect on the relay. This is shown in the. Phase overcurrent relays and residual overcurrent relays are often used to provide main earth-fault protec-tion of MV feeders.


  • Do the relay protection settings need to be checked three times

    Do the relay protection settings need to be checked three times

    A general rule of thumb would be to visually inspect every one to two years, secondary injection testing every one to three years, and primary injection every three to five years or on major changes. The standards dictate how accurate relays must be, the response time, as well as the condition they must withstand. We also acquire protective device requirements in electric. Protection relays employ a wide range of configurable parameters to identify defects & trip the breaker in a controlled & selected manner. PSM – Plug Setting Multiplier (Current Setting Multiplier) What is PSM? 2). Power system stability means also. However, the relay should be vigilant at all times. Setting determines pick-up value/time.
