What is TCS relay?

What is TCS relay?

Such Trip Circuit Supervision (TCS) relays are intended for a continuous supervision of circuit breaker trip circuit, and to give an alarm for loss of auxiliary supply, faults on the trip-coil or its wires independent of the breaker position, faults on the breaker auxiliary contacts and faults in the supervision relay …

What is high burden relay?

The High Burden Tripping Relay provides enhanced security in the substations and avoids opening of the circuit breaker due to capacitive discharge currents when there is an earth fault in long DC cables. The electrically or manually resettable latched trip relay RXMVC fulfill applicable international standards.

What is relay latching?

A latching relay is a two-position electrically actuated switch that maintains either contact position indefinitely without any power being sent to the coil and is a perfect choice to reduce the power consumption of a system. It is not necessary for power to remain applied to maintain the switched state.

What is a 52 relay?

52 AC circuit breaker A device that is used to close and interrupt an AC power circuit under normal conditions or to interrupt this circuit under fault or emergency conditions.

What is CT supervision relay?

Description. The 2V68 is a three phase monitoring device designed to provide continuous supervision of the CT circuits in high impedance differential protection schemes. The relay will detect open circuit conditions in the CT summation wiring and open circuited main current transformers.

What is Burden relay?

The load, or burden, in a CT metering circuit is the (largely resistive) impedance connected to the secondary winding. This means a CT with a burden rating of B-0.2 can tolerate up to 0.2 Ohms of impedance in the metering circuit before its output current is no longer a fixed ratio to the primary current.

How is the function of the digestive system controlled?

How is the digestive process controlled? Hormone and nerve regulators control the digestive process. The cells in the lining of the stomach and small intestine produce and release hormones that control the functions of the digestive system. These hormones stimulate production of digestive juices and regulate appetite.

What is the role of peristalsis in the digestive system?

Peristalsis also is at work in this organ, moving food through and mixing it with digestive secretions from the pancreas and liver. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.

How is the secretion of enzymes related to mechanical digestion?

Secretion of digestive enzymes and other substances liquefies, adjusts the pH of, and chemically breaks down the food. Mechanical digestion is the process of physically breaking down food into smaller pieces.

Which is an accessory organ of the digestive system?

Accessory organs include the teeth and tongue, salivary glands, liver, gallbladder, and pancreas. The treatment of food in the digestive system involves the following seven processes:
