Meter Installation

The installation of Glow Meters is quite straight-forward, however, please make sure that installation is performed by a licensed electrician.
If required, please contact us for recommend certified installers in your area.
Do not forget to Commission your meter immediatelly after installation.
Please see below the corresponding documentation.

Glow 285#

Single phase meter suitable for homes, small offices, and submetering of light loads, where the supply is 230V and loads are lower than 100 Amps

These types of meters require CT clamps to be connected to the meter, which its sizing will depend on the circuit's load. The choice of the CT clamp will also affects the measurement accuracy.

Selecting the right CT#

First of all, the CT clamp needs to have a secondary output of 5 amps (preferred) or 1 amp.
Then, the primary input will depend on the load of the circuit (rated current). In general, a good measurement accuracy is achieved by connecting a CT clamp with a primary output that's between 20% to 120% of the circuit's rated current.
As for the type of clamps, you can get a split-core CT for a convenient and non-disruptive installation, or a solid-core CT for a more permanent solution or when there's a need for space-efficient clamps.
Please feel free to contact us for recommend and tested CT clamps.
