Introduction

2 Introduction

2.1 Designated Use

2.1.1 Designated Use of the VOTANO 100/VBO1

The VOTANO 100 test set and the VBO1 voltage booster are intended to

perform guided testing and calibration of voltage transformers in laboratories as

well as on-site. The voltage transformers can be calibrated regarding to the ratio

error and the phase displacement. The following voltage transformers can be

tested:

• Inductive voltage transformers (VT)

• Capacitor voltage transformers (CVT)

• Coupling capacitor voltage transformers (CCVT)

For CVT/CCVT voltage transformers, please observe the restrictions in

section 2.2.

The following measurements can be performed using the VOTANO 100 and the

VBO1:

• Secondary short-circuit impedance measurement

• Secondary winding resistance measurement

• Secondary excitation characteristics measurement

• Transformer ratio measurement

The VOTANO 100 test set and the VBO1 voltage booster must only be used asa combination of these two devices. It is not permitted to use the VOTANO 100

or the VBO1 standalone without the other device connected properly as

described in chapter 3 "Setup and Test Preparation" on page 27.

The VOTANO 100 test set and the VBO1 voltage booster are exclusively

intended for the applications described above. Any other use is deemed not to

be according to the regulations. The manufacturer and the distributor are not

liable for damage resulting from improper usage. The user alone assumes all

responsibility and risk.

2.1.2 Designated Use of the VBO1 High-Voltage Cables

The VBO1 high-voltage cables are specificallydesigned for use with the VOTANO 100 and the

VBO1. These cables have to be used for the ratio

measurement and to short-circuit the primary

terminals of the voltage transformer during the

primary short-circuit impedance measurement.

The VBO1 high-voltage cables are exclusively

intended for this application. Any other use is

deemed not to be according to the regulations.




14

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 onthe 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 capacitorvoltage 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 additionaldevices 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.



15

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.

4.2 Simulation Mode

This section provides detailed descriptions for performing a simulation of the test

results based on ’real’ test results measured using the VOTANO 100 . Using thesimulation mode it is possible to simulate the behavior of a voltage transformer

with changed settings (for example, with a changed burden or for a changed

voltage factor Fv).

You can perform simulations using the results of the currently displayed test

(executed immediately before) or using the results of a test performed earlier

and stored on the Compact Flash card.

The following parameters can be changed in simulation mode (fields of editable

parameters are underlined by dotted lines in the user interface; display fields

that cannot be changed are not underlined).

Note: For more detailed information about a specific parameter, please refer to

sections 7.2 "Asset Card" on page 88 and 7.3 "Secondary Card" on page 91.

After changing a value, the VOTANO 100 recalculates the error tables and the

test assessment according to the changed values.

The SIM indication in the status line indicates that the VOTANO 100 is in

simulation mode.

Proceed as follows to perform a simulation:

Connecting and Disconnecting the Test Object

5 Connecting and Disconnecting the Test

Object

The proper connection of the test object to the VBO1 voltage booster depends

on the specific measurement performed by the VOTANO 100 during the test

sequence.

The VOTANO 100 therefore requests according rewiring prior to each

measurement. The measurements are executed in the order of the sections

below.

WARNING


Make sure that the terminals of the test object to be connected to the VBO1

do not carry any voltage potential. Make sure that the test object is completely disconnected from the power

system.

During a test, the VOTANO 100/VBO1 is the only permitted power source

for the test object.

WARNING


As long as the red LED is flashing, the output is active and lethal voltages can

occur due to the high energy stored in external inductors.

Never connect or disconnect measurement leads while the red LED on the

VOTANO 100 is flashing.

Wait until the red LED is off.

WARNING


Some measurements may charge the voltage transformer under test with a

high amount of energy. The VOTANO 100 then possibly requires some time to

dissipate the energy stored in the test object. In this case, a corresponding

warning (Warning 903.000) is displayed.

Do not touch the test object, disconnect measurement leads or switch off

the VOTANO 100 while the warning 903.000 is displayed.

Wait until the warning disappears.

5.7 Connection for VT Ratio Measurement

The VT ratio measurement has to be performed for every secondary winding of

the voltage transformer (CVT/CCVT or VT).Figure 5-10 on page 63 and Figure 5-11 on page 64 show the basic test setup

for a VT and a CVT/CCVT with one secondary winding. If the voltage

transformer under test has more than one secondary winding, further

measurements are necessary as shown in Figure 5-12 on page 65.


If the test object is a CVT/CCVT, the last measurement performed was theCVT/CCVT inductive ratio measurement (see section 5.6 on page 60). In this

case, no changes are required to perform the VT ratio measurement. Start the

test and continue with step 12 below.

If the test object is a VT, the last measurement performed was the excitation

9.3 Measurement Inputs

9.4 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
