Pick Up Current Current Setting Plug Setting Multiplier And Time

Relay protection three-stage protection setting values

Use this Protection Relay Setting Calculator to calculate pickup current, time multiplier settings (TMS), operating time, coordination time interval (CTI), and plug setting multiplier (PSM) using fault current, CT ratio, and IEC 60255 curve parameters. Purpose: Quickly clears severe faults near the relay (e. Limitation: Covers only ~80% of the line length, leaving a “dead zone” at the far end. Stage Ⅱ (TimeDelayed Overcurrent Protection) Purpose: Protects the remaining 20% of the line and acts as backup. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A straightforward way of obtaining selective protection is to use time grading. The principle is to grade the operating times of the relays in such a way that. 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). Time-Delayed Overcurrent Protection (Stage 2): Includes a short.
