Quick overview

The Iskra MT174-T1 is one of the most versatile three phase meters on the market and can be configured to show a number of different electrical parameters to suit a wide variety of applications. These include billing for consumption, measuring imported and exported energy on renewable installations, logging dual rate readings for tariff’s such as Economy 7 as well as measuring most of the common electrical parameters such as Energy (kWh), Power (W), Current (I) & Voltage (V) to name just a few. A recent addition to this list is a “Net” energy reading which is a common requirement for many renewable applications such as battery storage.

This Iskra MT174-T1 is a CT operated three phase meter manufactured by Iskra, one of Europe’s largest electric meter manufacturer’s.  This class B, (accurate to within 1%), surface mounted meter is MID approved making it suitable for billing applications and includes two pulse outputs and an RS485 connection.  While typically used in three phase four wire installations, it can also be used on both single and two phase supplies. It also logs recorded data internally so in the event of a fault, such as a screen failure, readings can still be retrieved.

We configure the auto scroll display, (viewable without having to press any buttons), on the MT174 for different applications as listed below.  This ensures the key information required is available without having to check instructions, press buttons etc.
