IDMT Relay Tripping Time Calculator

Inverse definite minimum time (IDMT) relay is a form of overcurrent relay that operates in inverse time fashion with the current in the protection system. Basically, with the change in the peak value of the current, the time required for the relay to perform is decreased. The measurement of operating time starts immediately when the …

Amps to Kilowatts Converter

During electrical power calculation, typically we use the normal calculator, in which sometimes we make mistakes during ac power calculations. Ac power consists of a power factor which we have to take into consideration. Again for three phase we have consider root 3 facor. This simple calculator will reduce the possibility of making an error …

thermal overload relays

Why is both RTD temperature and thermal overload protection needed?

Although both methods give protection against overload and thermal rise, both have their own pros and cons. Especially with the important objects, both methods are used because they complement each other. RTD basics We know metal has the property of varying resistivity with respect to temperature. This relationship is linear for some metals, over wide temperature …
