Switch Analyser SA10

Switch Analyser SA10


The SA10 equipment is designed to be used together with a personal computer even in those cases where fundamental tests can be performed without human presence (standalone).

There are many advantages to using a personal computer: versatility, customized solutions, simplicity...

Just take the computer to your office, select the tests, analyze test results, print test reports, etc.

Together with the BTS11 software, a personal computer and a printer, this is the most reliable, capable, accurate and easy-to-use field switch test equipment available on the market. Experienced engineers and service personnel have used the SA10 for many years in some of the world's harshest environments and have given it a good positioning in the world market.

General features

  • Housed in a small metal carrying case.
  • Fully compatible with our online factory test equipment
  • No switches on the panel, just two buttons that are pressed to open and close.
  • Supports digital and analog transducers
  • The only field test equipment with a built-in micro-ohm measurement function. 200A!
  • Possibility to use the "first shot" analysis method
  • It weighs only 11.6 kg/26 lb.
  • Automatic current/voltage measurement of coil and motor.


After switching e.g. capacitor banks, shunt rectors and power transformers it is common to use a synchro-switch relay for the circuit breaker.

The SA10 allows complete analysis of the wave point manoeuvring technology.


The equipment comes with a standard RS232 communication interface. However, in order to comply with safety regulations, a bluetooth communication kit is available that allows the user to move away with their laptop up to 100m (328ft) from the test object.

Static and dynamic resistance

This unique field test equipment with a built-in micro-ohmmeter is a complete and versatile unit. It generates 200 ADC and the value is automatically recorded

in the system along with their other measures. In order to visualize the exact behavior of the switch's pole during an operation, the dynamic resistance measurement function offers great diagnostic possibilities.


Motion measurements

The SA10 supports both analogue and digital transducers. A wide range of transducer couplings can be supplied. Elcon International is the official worldwide supplier of transducer couplings for ABB circuit-breakers.

Number of inputs on digital transducers: 3.

Number of inputs on analogue transducers: 3.

Analog inputs

Everything on all SA10's has 11 analog inputs, however as our intention is to provide you with a user-friendly and circuit-breaker oriented test set they have been pre-set to handle specific relevant functions such as coil and motor voltages, currents, analog signal transducers, etc. Of course it is possible to adjust most of the inputs to handle other types of related input signals, such as pressure or temperature sensors or any other type of analog signal that is relevant.


First shot or online analysis

In order to fully evaluate the condition of the breaker mechanism, the SA10 provides inputs to test the breaker during an on-line operation. This way, the first trip of a breaker that has been stationary for a long time can be captured and through that display determine the performance of the breaker in an actual fault situation. Both trip and close operations are possible online.

Contact time

The contact input modules of the SA10 supply 120 VDC on open contacts and 100 mA on closed contacts. The evaluation logic also distinguishes between a possible pre-insertion and the main contact in the same operation. It is also possible to measure the value of the pre-insertion resistor with a reference shunt. The time for both the pre-insertion and the main contact is guaranteed in any substation yard and at any voltage level.

Number of main contact time channels: 12(x2)

Number of auxiliary contact channels: 6.

(The auxiliary inputs can also be used as main contact inputs in low induction environments).

Coils and Motor

Automatic measurement of motor and switch coil current/voltage. Together with an adjustable power unit it is very easy to perform minimum function voltage test on the coils.

The SA10 uses an analog channel to measure coil voltage and current, and a channel to measure motor voltage and current.

For the coil 35A AC/DC for continuous measurement is possible, and for the motor 50A AC/DC. However, if required, higher currents will be passed through for shorter periods.

BTS11 System Software

BTS11 Test Program

For complete testing of the breaker, the BTS11 analysis software is used. The software is free of charge and is delivered together with the SA10. This software is used for Elcon field test equipment as well as for factory test equipment. The data between the two different systems can be easily imported/exported. All updates are free of charge and can be downloaded from our website.

To test switches in general, it is to operate the switch and check the contact time. However, in factory testing and field service other tests are needed. For field testing these other tests can also be very useful for diagnostic purposes.

Common operating tests can be done with resulting time diagrams for up to three phases, each with a travel curve, up to twelve contact curves and a common coil current curve. All common tests are performed and evaluated according to established industry standards. A new test, mainly for field diagnostics, is to take dynamic resistance test curves from a main contact in operation. A spring tension test, with current time diagram is also included.

One of the main intentions with our software is to allow any level of user to be able to test the switch. This is done by creating a database of your breaker types and allowing the user to choose their breaker from that database and having everything (test plan, test reports, parameters, etc.) automatically adjusted to meet that test.

Let's keep it simple.

Some features of the BTS11:

  • Simple operation control function for all possible tests.
  • Quick test. No adjustments needed.
  • Possibility of automatic test sequences.
  • Test guides for new tests and test objects.
  • Curve analysis window with many possibilities and tools
  • Data analysis function with limit monitoring and comparison possibilities with a pre-test. (Reference characteristics IEC62271-100).
  • Possibility to customize any operation in order to adapt the software to any type of switch.
  • Statistical analysis.
  • SQL database or access database with several users and user levels
  • Import and export of test data.
  • Automatic unit conversion. (ex: kg to lb or mm to inches).
  • Test against function values (measurement limits)
  • Easy to establish your own test profile.
  • Attach photographs or reference documents to assist the user.

EC - Elcon Competence Center
