he Summarize Measurement and Protection Unit (SMPR-1) has been designed to measure the line and ground RMS currents and supply RMS voltages under normal conditions or under disturbances. The voltage and current signals are sensed throughout potential transformers (PT) and current transformers (CT) from each line. This information is internally processed by the microprocessor, to take the current protection actions defined under ANSI, IAC or IEC standard. Additionally the operational conditions of the breaker or disconnector are also signalized. The different functions provided by the SMPR-1 may be classified into the following groups:
Applications:
* Primary and backup protection for power plants, utility and industrial distribution systems.
* Protection of transformers, overhead lines, cables and generators.
* Permits the opening of the switch/disconnector within the limits of its capacity, those identifying the excess (e.g. straight short-circuits), leaving the circuit interruption to the back-up fuses.

EMT - One Unit Affording Multiple Protection
Remarkable functional versatility in the smallest possible space: the EMT 6 thermistor overload relay protects machines against overtemperatures during severe starting duty, braking duty, undervotage and overvoltage, and high switching frequency.
The temperature is monitored by means of a thermistor, directly on the motor winding. In the event of overtemperature, the appropiate signal is passed to the EMT 6. It trips, and the fault is clearly displayed by an LED. Another field of application for the EMT 6 is the monitoring of temperatures in bearing, gearboxes, oils and coolants.
Devices for world markets
EMT 6 thermistor overload relays are, of cours, world market devices to IEC 947. In addition they also have UL and CSA approval, and Germanischer Lloyd approval. EMT 6 are finger- and back-of-hand proof to IEC 536.
Up-to-date PTB test reports even show that they are suitable for motor protection on machines in EEx e areas.
Universal and economical
Three types with differing functions are available: EMT 6, EMT 6-DB and EMT 6-DBK. The EMT 6-DBK is the most versatile with functions: automatic or manual operation, recognition of short circuits in the sensor circuit and zero-voltage safety. Zero-voltage safety ensures reliable fault signalling even in the event of supply voltage failure; signalling wich helps prevent expensive downtimes.
The EMT 6-DKB is suitable for every thermistor application. This universal device thus simplifies selection, engineering and stock-holding. For optimum safety, all EMT 6 thermistor overload relays have potential isolation between the sensor circuit and the control supply voltage.
