Do not use the product under conditions that exceed the range of its specifications. It may cause overheating, smoke, or fire. Do not touch the recharging unit while the power is on. There is a danger
If a Relay is selected that does not have the appropriate type of protection for the atmosphere and the mounting conditions, it may cause problems, such as contact failure.
Many of the protective relay systems are seldom called upon to work and have little means of proving they are in working order. Thorough installation testing and a preventive maintenance program verify
The major requirements on protection relays are speed, sensitiv-ity and selectivity. Fault calculations are used when checking if these requirements are fulfilled.
Relay protection is the discipline of designing schemes that detect faults, coordinate relays, and isolate equipment without outages. It emphasizes selectivity, coordination, fault response, and system
Hazardous voltages may occur and can injure personnel and/or damage equipment. Be careful when removing AC voltages from relays. Ensure that relays equipped with remote communication have the
Grounding electrical equipment is essential for the protection of personnel and devices. All metal parts of electrical equipment that are not intended to carry current should be grounded.
The ability to diagnose and understand motor overloads, short-circuit trips, motor starts, and all other relay operations has proved critical in the protection industry.
