Why is there a delay in restarting a compressor that has kicked off due to an internal overload?
Sequencer is out of sequence

Why is there a delay in re-starting a compressor that has kicked off an internal overload?
an internal overload is based off of heat.High heat=overload opens.Heat has to dissapate and motor cool to safe temp before internal contacts will close.
What is the difference between a fuse and a time delay fuse?
A time delay fuse will not blow at the first sign of an overload. It will delay blowing just long enough to allow a motor to start or a compressor to startup.
When the contacts are engaged by the thermostat or manually is there a time delay before the compressor or fan come on?
Yes, if there is an anti recycle time delay in the unit. No if there is not. If there has not been sufficient time since the last off cycle and a new on command for the refrigerant pressures to equalize, the compressor will attempt to start but will fail several times on it`s internal overload protection device until the pressures are equal before it finally does start. Giving the appearance of a time delay, this situation however should not affect either the indoor or outdoor fan. So if there is a delay on the indoor fan starting, there is probably a delay timer which may even be built into the thermostat.
What is the function of the time delay Fuse?
The time delay fuse allows a momentary overload due to startup current.
What is the function of the current sensing relay in an oil safety control scheme?
The electrical control panel for a refrigeration unit using single or three phase power. The control portion has an oil pressure safety switch, defrost timer, temperature controls and perhaps a refrigerant pressure control in conjunction with the normal internal overload circuit breakers for the compressor. After operation of the refrigeration unit for a period of time, a defrost control device cuts off the compressor and turns on the electric defrost heaters. As the evaporator coils are defrosted, defrost thermostats open the defrost heater supply circuits. When the current sensing relay senses that all the defrost heaters have been shut off via the defrost thermostats, a time delay relay will return the refrigeration unit to the normal refrigeration cycle. The same current sensing relay will prevent false triggering by the oil pressure safety switch if the compressor's internal overload circuit breaker opens
Why there is a time delay in the overload fault?
Most overload faults are isolated through a circuit breaker operating on a inductive trigger. Inductors take time to build up their magnetic field related to the total circuit resistance. The lower the overall circuit resistance and higher Henry value of the inductor, the longer it will take the magnetic field to develop. Electric motors and compressors for instance pull a very heavy load at startup. You need a time delay fuse as a normal fuse would blow every time the motor or compressor started.

Overdrive, Delay and a Compressor.
What is the definition of current trip overload or overloaad trip?
i think the meaning of that is a various types of time delay are used for overload trips to ensure that the generator breaks will not open due to a momentary current surge, but only if the excess current persist.....thats all.... :)
Difference between loss systems and delay system?
1) In a loss system overload traffic is rejected without being serviced. In a delay system overload traffic is held in queue until the facilities become available to service it.2)conventional circuit switching operates as a loss system since excess traffic is blocked and not serviced without a retry on the part of the user. Store-and-forward message or packet switching obviously posses the basic characteristics of a delay system3)The basic measure of performance for a loss system is the probability of rejection(blocking probability). A delay system on the other hand is measured in terms of service delays.
