3 സുരക്ഷാ വിവരങ്ങൾ

WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel.

• Always de-energize the primary circuit before installing or servicing the current transformer.
• Never open the secondary circuit of an energized current transformer. This can lead to dangerously high voltages and potential injury or equipment damage.
• എല്ലാ കണക്ഷനുകളും സുരക്ഷിതവും ശരിയായി ഇൻസുലേറ്റ് ചെയ്തതുമാണെന്ന് ഉറപ്പാക്കുക.
• Verify the correct polarity before connecting the CT to metering or protection devices.
• ഇലക്ട്രിക്കൽ സംവിധാനങ്ങളുമായി പ്രവർത്തിക്കുമ്പോൾ ഉചിതമായ വ്യക്തിഗത സംരക്ഷണ ഉപകരണങ്ങൾ (പിപിഇ) ധരിക്കുക.

4. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും

Installation of the ABB Type CLE Current Transformer requires adherence to local electrical codes and safety standards. It is recommended that a certified electrician or qualified technician perform the installation.

1. സർക്യൂട്ട് ഡീ-എനർജൈസ് ചെയ്യുക: Ensure the primary circuit where the CT will be installed is completely de-energized and locked out according to safety protocols.
2. മൗണ്ടിംഗ്: Securely mount the CT using appropriate hardware. The CT is designed to encircle the primary conductor.
3. Primary Conductor: Pass the primary conductor through the center opening of the current transformer.
4. Secondary Connections: Connect the secondary terminals (X1 and X2) to the metering or protection device. Observe correct polarity as indicated on the nameplate (H1-H2 for primary, X1-X2 for secondary). X1 typically corresponds to H1, and X2 to H2.
5. ഗ്രൗണ്ടിംഗ്: Ensure the secondary circuit of the CT is properly grounded at one point, typically at the X2 terminal, to prevent high voltagഇ ബിൽഡപ്പ്.
6. കണക്ഷനുകൾ പരിശോധിക്കുക: Double-check all wiring for correctness and tightness.
7. വീണ്ടും ഊർജ്ജസ്വലമാക്കുക: Once installation is complete and verified, the primary circuit can be safely re-energized.

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

The ABB Type CLE Current Transformer operates passively by inducing a proportional current in its secondary winding based on the primary current flowing through its core. Once installed, it requires no active user intervention for its primary function.

• നിരീക്ഷണം: The output of the CT (typically 5 Amps at rated primary current) is fed into a connected meter, relay, or other monitoring device. Refer to the instruction manual of the connected device for its operation.
• Load (Burden): Ensure the connected load (burden) on the secondary circuit does not exceed the CT's rated burden (e.g., B0.1 through B1.8 as indicated on the nameplate). Exceeding the burden can lead to inaccurate readings and potential damage.
• ധ്രുവത: Correct polarity is crucial for accurate directional measurements and proper operation of protective relays.

6. പരിപാലനം

The ABB Type CLE Current Transformer is designed for long-term, reliable operation with minimal maintenance. However, periodic inspections are recommended to ensure optimal performance and safety.

• വിഷ്വൽ പരിശോധന: Periodically inspect the CT for any signs of physical damage, discoloration, or loose connections.
• വൃത്തിയാക്കൽ: If necessary, gently clean the exterior of the CT with a dry, lint-free cloth. Do not use abrasive cleaners or solvents. Ensure the power is off before cleaning.
• ടെർമിനൽ പരിശോധന: Verify that all secondary terminal connections remain tight and free from corrosion. This should only be done with the primary circuit de-energized and the secondary circuit shorted or connected to a safe load.
• പരിസ്ഥിതി വ്യവസ്ഥകൾ: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature degradation.

7. പ്രശ്‌നപരിഹാരം

Most issues related to current transformers stem from improper installation or external circuit problems. Always prioritize safety when troubleshooting.

If troubleshooting steps do not resolve the issue, contact ABB technical support or a qualified service professional.
