What is meant by "tampering detection" of a electrical
energy meter?
Answer Posted / govind singh chouhan
The tampering detection in electrical meter is a function that log the tampering events when the tampering occurred.
means if you tamper the meter by applying the magnet then the meter is logged the magnet tamper with date and time and meter may start to register the energy on maximum load (240V and 60A).

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
