Key Features & Advantages
- Compact and scientific structural design allowsfor convenient and flexible installation;
- Advanced space voltage and current vectorcontrol algorithms, as well as selection ofstable voltage and current working modesensure your control requirements;
- The functions of overvoltage, undervoltage,overcurrent,over temperature, EMl suppression,fault locking and display ensure the safety ofsystem operation and the convenience ofmaintenance.
- High Current Output:
The core feature is its ability to deliver up to 1000 Amps of continuous or timed DC current. Some systems can even provide short-duration peak currents higher than 1000A.
- Stable and Regulated Output:
Sophisticive electronic control ensures the output current remains stable and precise, regardless of changes in the resistance of the test circuit (DUT). This is crucial for accurate measurements.
High Power Capacity:
To drive 1000A through very low-resistance circuits, the system has a high power rating.
- Programmable Control:
Modern systems feature digital interfaces (touchscreens, remote software) that allow users to program complex test sequences. .
Integrated Measurement and Data Logging:
The system includes precision shunts or current transformers (CTs) to measure the exact current flowing through the device under test (DUT).
- Robust and Portable Design:
Despite their high power, these systems are engineered for portability, often built on wheeled carts for use in switchyards, substations, and manufacturing facilities.
- Safety Features:Emergency Stop (E-Stop) Buttons:For immediate shutdown.Overcurrent and Overtemperature Protection:Safeguards the equipment from damage.
Operating Conditions
1. Environmental Conditions
Location:Must be used in a well-ventilated, dry area.
Temperature:Operate within the manufacturer's specified temperature range (typically -10°C to 50°C). Avoid condensation
2. Electrical Supply & Grounding
Input Power:Requires a stable AC power source as specified (220V/50A or 440V). The outlet or connection must be rated for the high input current required to generate 1000A DC output.
3. Device Under Test (DUT) & Connections Conditions
DUT Status:The circuit or assembly containing the DUT (e.g., a circuit breaker within a switchboard) must be completely de-energized (locked out/tagged out - LOTO). Verify absence of voltage with a multimeter.
4. Safety Conditions (PARAMOUNT)
Personal Protective Equipment (PPE);
Arc-Flash Rated Clothing and Face Shield.
HV-rated glovesto protect against accidental contact.
Safety glasses.
Additional Information
Operational Workflow
Planning:Review the test plan. Know the expected test current and duration for the DUT.
De-energize & LOTO:Isolate the DUT from all power sources and apply LOTO.
Connect Ground:Connect the tester's ground lead first.
Connect Test Circuit:Connect the heavy-current leads securely to the DUT (e.g., input and output of a circuit breaker). Double-check all connections for tightness.
Final Safety Check:Verify the area is clear. Ensure all personnel are wearing appropriate PPE.
Power On & Set Parameters:Turn on the tester. Use the controls to set the desired current (e.g., 1000A) or a ramp-up profile.
Perform Test:Initiate the current flow. Keep the test duration as short as possible(e.g., just long enough for the breaker to trip or to get a stable reading). Monitor for any signs of overheating (smoke, smell).
Terminate Test:The tester may stop automatically when the DUT trips, or you must stop it manually. Allow the current to ramp down.
Discharge & Ground:After the test, the internal capacitors may hold a charge. Follow the manufacturer's procedure to ensure the unit is safe.
Disconnect:Disconnect the high-current leads first, then the ground lead. The DUT and leads will be extremely hot; allow sufficient time for cooling before handling.
