Callout System for Phase Loss Protection

[Sunny_92]

I have a customer who would like to add phase loss protection to their service, with the added function of calling out to a phone number to alert someone when a trip occurs. Does anyone have any suggestions for implementing this?

I imagine we can add a typical phase loss device and capacitor trip device to the main, and use a separate device to perform the callout. However, I'm not familiar with any devices that perform this function.

Is there a relay available that can perform both the phase loss protection and callout?

I'm assuming we'll need some sort of battery backup for the either route. I'm also guessing that we'll have the option of using the landline or a cellular network.

Any general info or suggestions would be greatly appreciated, thanks!

Look at auto dialers

Have info on the existing system? That would help.

There are actually two pieces of equipment that we would like to add phase loss protection to. However, they are in separate rooms and may possibly be in separate buildings (I haven't been on site myself yet so I'm not sure).

1. 480V, 1600A GE Type HPC Switch

2. 208V, 2000A GE Type HPC Switch

I'm currently awaiting a response from GE on if & how we can shunt trip these switches.

The GE switches definitely have Shunt Trips available for them, but you will need the capacitor trip unit or a DC shunt trips coil and a battery backup, etc. You can also consider an Under Voltage trip coil, it doesn't need any added devices.

As mentioned, most Autodialers will come with a power loss call out feature built-in, so all you would need to do is power the Autodialer from behind the main disconnect somewhere so if the main trips, the Autodialer loses power can starts calling.

I have used Raco Autodialers for upwards of 30 years now years, they are very reliable, I highly recommend them.

The Levition SPDs that I use (32,000;42,000; series all have dry contact relays that can be used as an input to a dialer. these SPDs will give indication for power loss, and phase loss. they would connect to a branch circuit, 3 phase. Or use a phase monitor relay, such as Diversified/ATC

I am familiar with the Raco products, its a long established line, thats a good recommendation.
If the buildings have a monitored security alarm, the SPD could be connected as a zone, and the alarm monitoring company would get instructions on who to call if that zone is tripped

You can add a shunt trip to those (Or a UV) and add an aux switch to use with your auto dialer. Pretty simple job actually.

You might already have a ST and/or Aux installed. What is the catalog # of your HPC switches?

But as I said, MOST autodialers ALREADY trigger on a loss of power, you don't need to "tell" it that, as long as you don't put the autodialer on a UPS. If you do, THEN you will need an input from something to let it know.

Do they trigger specifically on phase loss or is the assumption made that a phase loss relay will kill all the power?
