I. General Information
GDSL-BX-200 Primary Current Injection Test Set, is mainly used for testing current transformer, motor protector, air switch, switch cabinet, circuit breaker, protection screen and etc.
II. Features
- PVC panel, simple and neat.
- With low power, big capacity autotransformer regulator and converter inside.
- Quick connects, lock design, good current-through capability.
- Built-in quick plug with high safety, to ensure reliable cable connection and improve test efficiency.
- Current range can be changed, easy to read.
- Engineering plastics box, dust-proof and waterproof, IP67 class.
- Portable design, suitable for on-site testing.
- Damping design, to ensure reliable transportation.
- Zero start function to prevent the test objects from damage caused by high current impulse. The equipment only can be started from zero.
- Impulse selection function. The required current can be output directly without zero protection function when making quick-break testing for circuit breaker.
- Accurate measurement. LCD digital indicator to display output current and voltage. The resolution of output current is 1A.
- Output 0-50A AC current, suitable for over current quick break testing of secondary protection.
- Action time can be tested synchronously.
- More calibrations can be series connected at the same time to improve working efficiency.
- Directly display primary current and secondary current, convenient for CT/PT turn ratios calibration test. (Optional)

Frequently Asked Questions (FAQ)
What is the primary application of the GDSL-BX-200 Primary Current Injection Test Set?
The GDSL-BX-200 is designed for testing current transformers, motor protectors, air switches, switch cabinets, circuit breakers, protection screens, and other similar electrical equipment.
How is the output current configured on this test set?
It supports two output modes: up to 0-1000A AC when connected in parallel, and up to 0-500A AC when connected in series configuration.
Does the device feature safety protections for testing?
Yes, it includes a zero start function that requires the system to begin outputting from zero voltage, preventing sudden high current impulses from damaging the test object.
Can this test set be used for field or on-site testing?
Absolutely. The device features a portable, damping design and is housed in an IP67-class engineering plastic box that is both dust-proof and waterproof, making it ideal for on-site operations.
What is the testing cycle rule for batch testing?
For batch tests, the recommended duty cycle is 2.5 minutes ON and 10 minutes OFF to ensure safe and stable operation.
How does the impulse selection function work for circuit breakers?
The impulse selection function allows the user to output the required current directly without the zero protection function, which is ideal for performing quick-break testing on circuit breakers.
