MeterTest VTS High-Precision Voltage Separating Transformer ISO 9001:2000 Features: Typical accuracy 0.01% Easy assembly Direct work with all types of meters High output power Resistance to non-linear loads Integration with the system The VTS Voltage Separating Transformer was designed keeping in mind alternating current measurement systems requiring galvanic separation of the measuring circuits. The built-in electronic compensation system guarantees excellent parameters in the whole voltage range, ensuring at the same time high output power. Typical error 0.01% makes the device an ideal solution for a wide range of applications. Among them there is a possibility of using the transformer for testing electricity meters with closed I-P links i.e. meters with connected current and potential circuits. Broad range of working voltages, high output power and high accuracy enable the VTS transformer to be rigidly integrated with a meter testing system. Once integrated, it can handle all kinds of meters, also meters with open links, with negligible influence on the overall system accuracy. Special attention deserves the fact that this device, unlike the passive transformers, excellently copes with non-linear loads, which typical modern electronic meters are, not deteriorating its accuracy. This device is purposed for testing singlephase meters.
