Power meter

[empip]

Trying to max info from a Maplin Power Meter.

Surface mounted radial circuit.
Connections bright and tight.
Length 5.3 M within a centimeter or so.

Appliance rated 2700W at 240V.

Measured at the socket supplied.

No load 242.3 V

Load applied 10.9 A : 239.3 V

242.3 - 239.3 = 3.0 V

3.0 V / 10.9 A = 0.275 Ohms ..

Which resistances in total combine to produce the 0.275 value?

Measured at the socket supplied.

No load 242.3 V

Load applied 10.9 A : 239.3 V

Is the voltage INTO the meter constant at 242.3 V or does that also drop on load.

The voltage drop will be spread all along the conductor string from the network transformer to the pins in the socket.

Cheers B,
The meter reads volts (off load) 242.3V
On load (10.9 A) the meter reads 239.3V.

So I am not just reading the resistance of the cable from DCU?
deleted silly line.

Does the appliance plug top and lead etc have an effect?

Cheers. E
