CPC CABLE stands for Circuit Protective Conductor cable, which is used for earthing and providing protection against electric shock.
CPC CABLE is also known as the earth wire in electrical installations.
It is typically colored green and yellow to distinguish it from other cables.
The CPC CABLE is connected to metal parts of electrical equipment to prevent electric shock in case of a fault.
High pot test is done to check the insulation of electrical equipment.
High pot test is done to ensure the insulation in electrical equipment can withstand high voltage without breaking down.
It helps in identifying any weaknesses or defects in the insulation that could lead to electrical hazards.
The test involves applying a higher than normal voltage to the equipment to see if the insulation can handle it.
High pot testi...
HT cables are high tension cables used for transmitting electricity at high voltages.
HT cables are designed to carry high voltage electricity, typically above 11kV.
They are insulated to prevent leakage of current and ensure safety.
HT cables are usually made of materials like cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR).
They are often armored to protect against physical damage and environmental fa...
RCBO combines the functions of an RCD and a miniature circuit breaker, while RCCB and ELCB are older versions of RCDs.
RCBO combines overcurrent protection (like a circuit breaker) with earth fault protection (like an RCD)
RCCB is an older version of RCD that only detects earth faults
ELCB is an even older version of RCD that detects earth faults by measuring the current imbalance between live and neutral wires
RCBO is com...
The ten delta test is a diagnostic test used to assess the condition of power transformers.
The ten delta test measures the change in power factor between the initial and final stages of a transformer's life.
It is used to detect insulation deterioration and moisture content in the transformer oil.
Equipment used for the ten delta test includes a power factor test set, a transformer turns ratio tester, and a megohmmeter.
UPM in data centre involves managing electrical systems, ensuring uptime, and implementing energy efficiency measures.
Managing electrical systems to ensure continuous power supply
Implementing energy efficiency measures to reduce costs
Monitoring and maintaining backup power systems
Troubleshooting electrical issues to minimize downtime
Coordinating with other departments for electrical maintenance schedules
Isolation transformers are used to isolate electrical devices from the power source for safety and protection.
Isolation transformers have primary and secondary windings that are electrically separated to prevent direct current flow between the input and output.
They are commonly used in medical equipment, data centers, and sensitive electronic devices to protect them from electrical noise and voltage spikes.
Isolation tr...
