High Voltage NC Relay config

[Ray77]

Hi all,

New to here so Hello and thank you in-advance for any information given.

I have a HAL Clare Tester and need to split the live feed to a normally closed high voltage relay to simulate a switched live. The idea is the power will go through L and L1 and then turn off the switched live for a few seconds and then back on. Anyone ever done such a setup and would love any feed back concerning components needed and setup. There is a digital out signal I can use from the tester if needed.

Once again thanks for any information supplied and hope I can help others in the future.

What do you class as “high voltage?” For most it’s equipment that is rated ≥1000V, your tester isn’t up to that.

You need to give more details.

Thank you for your reply Tony S

The tester is a SEAWARD HAL LED Claire Tester and here is some information from the Spec. 

• Test Voltage: 6V AC Nominal
  
• Output Current Range: 0.1A – 40.0A
  
• Programmable Voltage Range:
  
  
  
  0.10kV – 5.00kV
  
• (10V/step manual)
  
• (50V/step auto)
  

[*]DC Output Voltage

• 
  
  0.10kV – 6.00kV
  
• (10V/step manual)
  
• (50V/step auto)
  

[*]Test Voltage:

• 
  
  110V – 230V AC (Mains Supply)
  
• 80V – 250V (Via Auxillary Input)
  
• 20A nominal (Vin-Vout)

would it not be worth contacting Seaward ?

Hi Binky,

I have and this was their reply.

The manual switch is obviously more simple to set-up but the process itself will be less streamlined and susceptible to human error if the switch is incorrectly switched. You simply need to install a switch after splitting the live from the HAL to L and L1, allowing you

To set up the relay you would use the digital out signal from the rear of the HAL to a normally closed, high voltage relay which would then open and essentially simulate the switched live being turned off.

In either case you would only need off the shelf components from any decent electrical wholesaler, we do have a switching matrix that could do this but they are around £2,400 which may be a little overkill for this implementation

Ill call them if I need but was trying to see what info was around.

Thanks

Many moons back I wrote a test procedure for 3.3kV breakers, I’ll see if I can find it. I retired 8 years ago so don’t hold your breath.

Thanks you Tony. All help is appreciated.

It would help to know what this “relay” actually is.
