Vanguard DIGITMR S2 Circuit Breaker Tester from the United StatesOnline timing mode

In addition to the traditional offline timing mode, DIGITMR
S2 also offers an optional "online" timing module
Formula. In this mode, DIGITMR S2
Collect data from the circuit breaker during its operation
Jumping/closing time, jumping/closing coil current "refers to
Pattern "and power supply voltage. Jumping/Closing
Time starts from the start of the tripping/closing coil and ends with the use of
A clamp shaped AC ammeter senses the circuit breaker
The current in the bushing corresponds to the one that starts the circuit breaker
A time.
The "online" timing mode can detect a break
There are few or almost no faults or shutdowns in the circuit breaker
The operational status. In this mode, the circuit breaker
*The time of the second (trip) tripping action can be captured
Caught it. When a circuit breaker is put into operation for a long time
When the value is in the closed position, due to the machine
The reason for the stickiness of the equipment, * times after the circuit breaker
The tripping time may be longer. “
Is the online mode right or wrong in situations like this
Often useful because traditional circuit breaker timers
It's impossible to detect this situation when they detect it
Before the tripping time, it was kept closed for a long time
The circuit breaker in the state has actually been activated several times
That's it.

Self diagnostic ability

DIGITMR S2 is capable of detecting the electrons inside it
Perform self diagnosis on electronic components. Diagnosis can be used
To verify the connection status of the contact cable and measure
The quality of the electronic components of the test travel sensor
The situation.

Current monitoring of tripping/closing coil

A built-in Hall sensor records tripping/closing
The amplitude and duration of the coil current. open circuit
The waveform of the action coil (equivalent to coil nature)
Capable of "fingerprint" or "current profile"
Can be used as a diagnostic tool to analyze the performance of circuit breakers
The tool.

Voltage monitoring input

An analog input channel V1 dedicated to monitoring
Measure the DC power supply voltage or coil voltage (0-255)
Voltage, DC or AC peak). another
Voltage input channel V2, dedicated to monitoring voltage
Present/absent status (indicating the auxiliary switch of the circuit breaker)
Whether it exists or not, it is used to monitor a type A/B
The status of the switch.

Internal testing records and testing plan storage

DIGITMR S2 can store up to 200 on its built-in flash memory
Up to 200 test records and 100 test plans can be obtained.
Usually, a test plan includes the performance of all circuit breakers
Parameters (travel, speed, and contact timing, etc.)
When conducting testing, the actual test data is compared with
Compare the stored test plans and generate a 'pass'
Test report of 'passed/failed'.
The testing plan is based on a matching Windows
The circuit breaker analysis application software of the system generates it
Can be accessed through USB or Bluetooth interface (optional)
, or upload to through an external USB flash drive
In the DIGITMR S2 instrument.
This external USB flash drive can store up to 999 units
Test records and 999 test plans.

Contact timing input

Dry contact timing channel, used for the movement of circuit breaker contacts
time. Each contact timing channel can detect the main contact
The movement time of the head and auxiliary resistor contacts, timing device
Display in milliseconds or cycles. DIGITMR
S2 has 3 available contact timing channels.

Circuit breaker travel and speed

There is a digital sensor input channel used to measure
Measure the stroke, speed, overtravel, and bounce of circuit breaker contacts
Jump. Using this travel sensor, before testing, neither
Verification is required and no settings are needed. It has a special nature
Yes, it is used for the "slow closing" test of circuit breakers and can
Obtain the test report. There is also an optional resistor type available
Sensor adapter, can be used with some resistive types
Sensors are docked.

Current Transformer Input

There is a non-contact AC current sensor that uses
Perform online circuit breaker operation in "online" timing mode
Monitoring of flow.

Starting characteristics of circuit breaker

DIGITMR S2 is equipped with a solid-state startup device,
Used for operating circuit breakers, the operating modes include tripping
Closing, reclosing, automatic tripping, and false closing. many
Heavy operation, such as reclosing, automatic tripping, and misoperation
The gate can be operated through a programmable delay timer
Or initiate with a specific switch contact state. sever
The amplitude and waveform of the current in the circuit breaker coil can be recorded
Get down and print it out on a thermal printer.
