transfer trip switch

Substation Design | Power System Analysis

Direct Transfer Trip Scheme

Direct Transfer Trips (DTT) are initiated from station relays when a severe event occurs in the substation. Some of these events are breaker failure, bus faults, transformer failure, etc. A lockout relay (86 device) is assigned to each event.

The lockout relay in the station is pretty essential. When operated due to any of the events indicated above, it trips all the breakers connected to it. So for example, for a bus fault, the bus differential relay will operate the bus lockout relay which will trip and blocks re-closing of all the breakers connected to the bus. If the breaker is at a remote location and can’t be physically wired, a DTT signal is sent to it via the protective relays using the pilot channel.

The figure below shows which all lockout relays are typically used to initiate the DTT. The substation design affects this. For example, a ring bus substation or a breaker-and-a-half substation has a breaker failure lockout assigned to each breaker. For other designs, a breaker failure event trips the bus lockout relay. Whichever case you are presented with, a contact from the lockout is assigned to the relay that can key the DTT signal to the remote end breaker.

Note that lockout relays are typically used to initiate DTT. In which case, the intent is to trip all breakers without any delay. There is no logic or reasoning – just trip. Remaining events like faults on lines are taken care of by the pilot schemes which have intentional delay for coordinating the breaker trips.

Direct Transfer Trip Quiz

Get ready to learn this topic like never before.

For what kind of fault at Substation 1 would you transmit a DTT to Substation 2 (to trip breaker 2CB1)?

For the fault scenarios listed, there is no way to stop the fault contribution from Substation 2. There is no breaker on the line-exit at Substation 1 (You cannot use a switch to interrupt load or fault current. Learn more ). If one existed, tripping it would suffice, and a DTT wouldn't be necessary.

For a temporary fault on the transmission line, would you transmit DTT from either one substation?

Faults on the transmission line are usually temporary. Line protection relays require time to implement its reclosing logic. DTT is not initiated.

Note that designing the protection system is an art and not an exact science. How the relay engineer "paints" differs from utility to utility. For instance, certain t-lines pass through a dense forest while others through an arid desert. The utility engineer dealing with the trees (causing higher temporary faults) may choose to go with reclosing logic - no DTT. In the case of the desert, the faults could be interpreted as permanent and whichever relay detects the fault using its Zone 1 elements, transmits DTT to the remote-end substation relay.

For a fault on Bus 1, would you implement a direct transfer trip (pilot) scheme to trip breakers tied to the same bus?

All breakers shown are within the substation. You can wire the trip 'a' contact from a lockout relay to breaker's trip coil physically. Therefore DTT scheme is not required.

For a transformer fault at substation 2, would you transmit DTT to substation 1?

Fault current contribution from substation 1 can be stopped by tripping 2CB1. DTT transmission to Substation 1 not required.

Fault current contribution from substation 1 can be stopped by tripping 2CB1. DTT transmission to Substation 1 not required.

Assume circuit breaker 3CB2 fails at substation 3. DTT is transmitted to Substation 2 to trip 2CB1 and 2CB3. Which auxiliary relay would you install at Substation 2 to trip breakers 2CB1 and 2CB3?

A quick word on 94 and 86.

94 relay - when its operating coil is energized - it trips. When de-energized, it resets automatically.

86 relay - when its operating coil is energized - it trips. When de-energized, it does not reset. Someone needs to be at the substation to reset it.

Considering the severe event did not occur at Substation 2, it makes no sense in installing a lockout at this station and needlessly sending someone to reset it. A  94 relay is used in this scenario. Some utilities may also use microprocessor relays to trip the breaker (instead of a 94 aux relay).

Common Issues with Transfer Switches and How to Fix Them

The whole point of a transfer switch is to make the process of switching your facility over to backup power automatic . That’s why it is incredibly frustrating when you have transfer switch issues . You’re dealing both with the loss of power from the grid and the failure of your backup system to take over or at least take over within a few seconds.

What has caused your transfer switch to fail? And how can you fix it? In general, this is a problem for the professionals . Repairs should always be handled by a certified, licensed and experienced electrician , or you risk harm to not just the person trying the repairs but also everyone in the building and, less significantly but still importantly, damage to your equipment.

While you shouldn’t attempt your repairs, it is still useful to know the common issues and how the professionals will fix them. It's empowering to better understand your equipment and have the terminology and understanding to ask your electrician your questions. So, here are common issues with your transfer switches and how to fix them.

1. Tripped Breaker

Power surges and overcurrents can trip the breaker which serves your transfer switch. When this breaker is tripped, your transfer switch cannot function properly. You should have your electrician check the breaker during the routine maintenance of the system.

2. Corrosion from Moisture, Leaks

Corrosion and shorts are commonly caused by exposure to moisture. Leaks, flooding, or just environmental moisture can damage your transfer switch and the wiring that serves it. You should check to ensure the transfer switch has proper environmental protections. After leaks or natural disasters, your entire electrical system should be checked, including the transfer switch.

You should not approach any wet electrical equipment. Allow electricians to do this, as they know the proper safety protocol that needs to be followed in order for them to stay safe.

3. Loose Connections from Dirt, Debris

Dirt and debris may also get into the transfer switch or interfere with its connections if the switch and the area, in general, are not well-maintained or not properly protected. Loose connections can cause the transfer switch to fail. So, your electrician should clean the area out and then test the contacts. When necessary, he or she will tighten the contacts to ensure they carry current.

4. Damage to the Controller

Controllers are an essential and sensitive component of a transfer switch which may fail over time or become damaged. You may need to repair or replace the controller.

5. ATS Issues

If the transfer switch turned your backup generator back on but didn’t turn it back off, even after its normal cool-off period should have ended, the most likely problem is an issue with the ATS. This tells the transfer switch to turn back to utility power and shut down the backup generator.

The ATS has had its own loose connections, or it may have been grounded somehow. In either case, an electrician can fix this problem.

6. Overheating

If your transfer switch was exposed to very high heat conditions, or it cycled too fast and created a great deal of heat itself, then it may burn out the solenoids or cause other serious heat damage. In this case, the transfer switch may stop working altogether. This issue usually requires replacement.

7. Improper Installation

If the transfer switch was installed recently and did not have the time to be tested before it was required, it is possible that the switch or some component of it was never installed properly in the first place. This is rare, but it does happen.

Also, another rare issue may be that the transfer switch has a manufacturer’s defect that prevents its use. In this case, your electrician should be able to diagnose the issue for you and advise you as to warranty issues or speaking with the manufacturer about the problem.

How Can You Avoid Transfer Switch Problems?

There are many other potential issues that your transfer switch may develop, and repair and replacement may be expensive.

Regular maintenance of your electrical system and regular testing of your backup supply, including your transfer switch, can ensure that it all operates properly and that you will have backup power when you need it.

How to Choose the Best Transfer Switch for RV

Wattage and amperes.

There is a huge variety of RV transfer switches in the market. But you don’t have to worry about them, as we’ll help you with it. It’s not hard to find one that fits your requirements.

To choose the transfer switch for your RV, check the wattage on your generator. For example, if your generator runs at, say, 2000 Watts, you should get a transfer switch with at least 2000 Watts.

But we’d recommend getting a transfer switch that has a higher wattage capacity than your generator. If you end up getting a lower wattage transfer, it’s as if you’re inviting trouble.

As for the amps of your Transfer Switch, there are two types, one with 30 amps and the other with 50 amps. Get one that fits your generator and rig.

Configuration status

Transfer switches are mostly pre-wired. But some of them aren’t wired, and those are the ones that you should avoid.

So, check thoroughly before getting a new transfer switch. Not only are the pre-wired transfer switches easier to install, but they also cost less to install too.

Safety is a huge factor in RV transfer switches. If the thing you are buying to keep yourself safe isn’t safe, how can you assure your safety?

You need to make sure the transfer switch that you’re buying is safe enough or not. They cause terrible accidents if any of their parts malfunction. So, a pro-tip is to get a safety switch that is certified.

Installation factor

When getting a transfer switch, you need to consider its installation factors, too, such as where you will mount the switch. And if it’ll need extension cords or not, where will be the inlet box?

If you properly consider these things when getting a transfer switch, you won’t find yourself running to the electric store repeatedly.

Construction

Sellers won’t usually mention the construction of a transfer switch. So, that’s why you have to check if the construction of the transfer switch is durable or not?

With this, you can be sure that it’ll last a long time without the need to replace it. In addition, you can examine its materials to make sure it’s durable.

If the seller is good, he’ll offer you options such as a normal or ‘heavy-duty.’ You should still check the components and their build quality. If you get your hands on an actual heavy-duty, it guarantees that it’s the last longing.

What are the different types of transfer switches for RV?

Transfer switches vary in manual and automatic. The types of transfer switches for RV depend upon the voltage needed. They can range from 30 amps to 100 amps.

And if you want to go for higher power, you can find one from 2KW to 20KW depending on your needs.

How does an RV automatic transfer switch work?

Transfer switches that are used in RVs prioritize generators. Usually, the switch will be connected to shore power even when no power is present.

But when there’s a voltage detected on generator inputs, it will drop to the shore power. These switches are made so that only one input can be connected simultaneously; this prevents any hazardous conditions.

Where is the transfer switch in an RV?

A transfer switch is positioned right before the breaker panel in the RV, hidden inside a cabinet or on the wall behind some object like the refrigerator.

How big of an RV transfer switch do I need?

You will need to calculate the load of your generator used in the RV, and for that, you need to match the largest outlet of your generator to the transfer switch. This will help you get the transfer switch of the size your RV requires.

How do I choose an automatic transfer switch?

The best way to choose an automatic transfer switch is to know your requirements. First, check how much load your generator has.

Then, make sure it can supply current for a reasonable amount of time, like 3 to 4 hours straight. Also, the current rating should match the use by the main breaker.

Leaving the comfort of homes is a significant accomplishment. It gives you enough time to think about yourself without any worries. But, of course, this can quickly change if you don’t prepare enough.

So, we recommend you get yourself an RV transfer switch for backup power. So, that fun can carry on even when power runs low.

Now, before getting one, read the whole guide thoroughly. And jot down essential points off it. So, when you go out to get a transfer switch, you won’t be fooled by the salesman.
