How do you calculate 3 phase motor overload relay setting?
overload model no Ke-FKR4(D)
What would you do to measure the current in a resistor?
Since the current in a resistor is the same as the current in the leads/wires on either side of the resister, I might use a clamp meter such as an Amprobe to measure current, if the current was alternating (AC). Otherwise, I would have to break one of the leads and insert an ammeter or a multimeter with an amp setting into the circuit. Afterwards the broken connection would have to be repaired.
How do you ctmm motor protection relay setting?
Just calculate from motorplate: Watts/(Square3*V*cosP)=> example motorplate says: 4.7Kw 440V cosP: 0.82 4700W/(square3*440V*0.82) here you get minimum setting for motor, this case 7.5A JT
What is high set and low set current setting?
The low-set stage is a current with a definite time or inverse-time operation. The high-set stage has a definite time characteristic only without the inverse-time operation.
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.
What is the formula to calculate the overload setting for a star delta starter?

What is plug setting multiplier of relay?
the actual r.m.s current flowing in the relay expressed as a multiple of the setting current (pick up current) is known as plug setting multiplier.mathematically ,PSM= SECONDARY CURRENT/RELAY CURRENT SETTINGorPSM= (primary current during fault)/(relay current setting *C.T ratio)
Is it legal to take a photo of someone with them knowing but not asking?
It depends on the location. If someone is clearly in the public setting, yes, you can take their picture without them knowing or asking permission. But if you are in private, no, you need their permission. You have an expectation of privacy in a private setting whereas, in a public setting, you do not.

1.What is a historical setting?
A. a setting from any time in an imaginary place B. a setting from a difficult time with great conflict C. a setting from the current time in a real place D. a setting from a past time in a real place
How do you calculate setting for over current earth fault relay setting?
An artificial neutral is crated in the CT of the line to be protected (for transmission lines) a CT is fixed in the neutral of the CT. if there is any imbalance in the 3 phase current then the relay will develop a difference in neutral.that can be sensed by the CT,then gives the trip command to relay
