VOTANO 100 User Manual
2.2
Test Restrictions The VOTANO 100 test set is designed to test voltage transformers (see section 2.1 on page 13) used in electrical power systems. The test concept is based on the mathematical model of a standard inductive voltage transformer and uses test signals below the nominal voltage and above and below the nominal frequency. The information below shall help to identify which types of voltage transformers cannot be tested with the expected accuracy (as stated in chapter 9 on page 113) or cannot be tested at all with the VOTANO 100 .
Inductive voltage transformers with open core design Such types of voltage transformers cannot be tested using the VOTANO 100 due to their special core design.
Capacitor voltage transformers (CVT) and coupling capacitor voltage transformers (CCVT) CVTs/CCVTs with an integrated damping unit that cannot be accessed from outside to open the damping circuit during the test cannot be tested accurately with the VOTANO 100 . The damping unit is frequency-selective and optimized to the nominal frequency of the CVT/CCVT. Measurements made with signals below and above the nominal frequency are therefore affected by the damping unit. CVTs/CCVTs where the connection of the NHF terminal to ground cannot be opened during the test cannot be tested with the VOTANO 100 .
Voltage transformers that are equipped with additional devices for turns correction Additional devices for turns correction installed inside the voltage transformer (for example, an additional inductive voltage transformer) might influence the VOTANO 100 measurement results.
14
Introduction
2.3
Definition: VT and CVT/CCVT VTs are usual inductive voltage transformers (so-called potential transformers (PT)). CVTs/CCVTs are capacitively coupled voltage transformers that use a combination of a capacitor voltage divider and a voltage transformer to step down high voltages. In the ANSI standard they are referred to as CCVTs. In the IEC standards they are referred to as CVTs. The following figure explains the difference between a VT and a CVT/CCVT.

Ratio and Phase Measurement Accuracy The VOTANO 100 /VBO1 test system is factory calibrated prior to shipment using an ISO 17025 calibrated reference voltage transformer. To assure the accuracy of the measurement results, it is recommended to verify the calibration at least once per year using a calibrated voltage transformer. If the measurement results are not within the given limits, we recommend to send the VOTANO 100 test set back to OMICRON for calibration (see "Support" on page 133). The VOTANO 100 uses a mathematical model based on the equivalent circuit diagram of an inductive voltage transformer to calculate the ratio and phase error. The stated typical accuracy values given for the ratio and phase error are

Solution: The mains supply does not have reference to protective earth or protective earth is not connected. The mains supply must have galvanic connection to PE. If you are using an isolation transformer, connect one supply line of the VOTANO 100 to PE. WARNING Death or severe injury caused by high voltage or current possible ►
►
Do not use the VOTANO 100 without a solid connection to protective ground (PE). Lethal voltages may occur at the housing if the grounding terminal of the device is not connected to protective earth potential. Always connect the grounding terminals of the VOTANO 100 and the VBO1 to protective ground (PE) using a solid connection of at least 6mm 2.
NOTICE Equipment damage or loss of data possible
Comment:
►
Do not use the VOTANO 100 with a mains supply that is galvanically isolated from earth potential. This could damage the device.
►
Only use the VOTANO 100 with a mains supply that is galvanically connected to PE.
If a galvanically isolated mains supply is used, voltage stress may occur for the insulation system, the device is not c onstructed for. Safety is no longer guaranteed! Therefore, always use a mains power cord with a protective earthing conductor connected to PE of the mains supply. Connect the grounding terminal of the device to protective earth in order to prevent electric shock caused by lethal voltages possibly present at the housing.
