Questions about this model
How do I get a price for the monitoring voltage relay
Email [email protected] or message us on WhatsApp with the model, the ratio, the accuracy class, the burden in VA and the quantity.
What is the burden and why do you ask for it
The burden is the total termination impedance seen by the transformer: the measuring instrument, the connecting leads and the winding itself. Accuracy class cannot be guaranteed without it, and long lead runs add resistance that has to be counted.
Can this model be customised
Ratios, secondary current and mounting can often be adapted within the same frame. Send us the requirement and we will confirm what the frame allows.
