What is psm tsm for idmt relay?

PSM stands for Plug setting multiplier and can be found on the front of the relay module in the form of a scale . PSM = Actual or fault current in the relay / ( CT Secondary current X Amp setting in the relay) From the above value of PSM find the time in seconds from the front of relay panel scale i.e., PSM Vrs Time in seconds Miltiply the time in seconds with the TSM to find the tripping time for the relay for the specific value of fault current TSM = Time setting multiplier Relay Operating time = TSM x time in seconds <- as observed from the scale .


What is plug setting multiplier of relay?

The plug setting multiplier of a relay is a ratio used to determine the pickup current of the relay based on the nominal current rating of the system it is protecting. It is calculated by dividing the full load current of the protected system by the maximum current that the relay can handle. This multiplier helps in setting the relay's pickup current level accurately for proper coordination and protection.


What is meant by time multiplier setting?

the time setting multiplier is the fraction of the full angular travel for one complete rotation that the disc will perform before closing the trip contact.


What is the theory behind a definite time overcurrent relay?

A definite time overcurrent relay operates like an instantaneous overcurrent relay coupled with a timer. once current reaches the pickup value, the relay overcurrent relay will trip, which initiates the timing circuit. as long as current stays above this pickup value, the timer will continue to time. Once the definite time setting is reached, the timer will close the relay tripping contacts.


What is pick up of a relay?

The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.

What item is used as both a distance multiplier and a speed multiplier?

The item used as both a distance multiplier and a speed multiplier in mathematics is the unit of a "mile." It is a unit of length that can be used to measure distances, and it is also commonly used in calculating speed where it is combined with time to measure the distance traveled over a specific time period.


What is the motherboard speed setting for a Pentium-200?

A Pentium 1 running at 200 Mhz (both MMX and non-MMX) requires a 66 Mhz bus and a multiplier setting of 3.


What is DTOC relay?

A definite time over-current relay operates like an instantaneous over-current relay coupled with a timer. Once current reaches the pick-up value, it initiates the timing circuit. As long as current stays above this pick-up value, the timer will continue to time. Once the definite time setting is reached, the relay gives trip signal to the circuit breaker.
