Numerical and microprocessor relay comparison?

Numerical relays are all microprocessor based, but there are relays that take the advantage of microprocessor technology and are not fully numerical. In other words, if a relay is fully based on processing the samples of input signals it is numerical relay.

Why you need calibration for earth fault relays?

Electromechanical relays (not just earth fault relays) need to be calibrated to insure they are operating in the expected way. A simple overcurrent ground relay will have a tap setting, and a time dial setting. These are chosen by a protection engineer to coordinate with other ground protection devices upstream and downstream. If the relay is not calibrated correctly, the relay will not operate at the expected tap value, or may operate slower / faster due to the time dial calibration being different than expected. This can cause over tripping, removing more equipment from the power system than is necessary to clear a fault.

How do you adjust the calibration of pocket scale?

To adjust the calibration of a pocket scale, you will typically need a calibration weight that matches the capacity of your scale. Place the calibration weight on the scale and follow the instructions in the user manual to calibrate it by adjusting the calibration setting until the scale displays the correct weight.

Does a humidity sensor need calibrating?

Yes, a humidity sensor may need calibration to ensure accurate readings over time. Calibration involves adjusting the sensor to a known reference or standard to minimize errors in humidity measurement. Calibration is essential for maintaining the sensor's accuracy and reliability.


What is Numerical Relays?

These are microprocessor-based relays in contrast to other relays that are electromechanically controlled. These relays provide great precision and convenience in application in the sophisticated electronic products. By combining several functions in one case, numerical relays also save capital cost and maintenance cost over electromechanical relays. The first protection devices based on microprocessors were employed in 1985. The widespread acceptance of numerical technology by the customer and the experiences of the user helped in developing the second generation numerical relays in 1990. Modern power system protection devices are built with integrated functions. Multi-functions like protection, control, monitoring and measuring are available today in numeric power system protection devices. Also, the communication capability of these devices facilitates remote control, monitoring and data transfer. Traditionally, electromechanical and static protection relays offered single-function, single characteristics, whereas modern numeric protection offers multi-function and multiple characteristics. Some protections also offer adaptable characteristics, which dynamically change the protection characteristic under different system conditions by monitoring the input parameters. The measuring principles and techniques of conventional relays (electromechanical and static) are fewer than those of the numerical technique, which can differ in many aspects like the type of protection algorithm used, sampling, signal processing, hardware selection, software discipline, etc. First generation numerical relays were mainly designed to meet the static relay protection characteristic, whereas modern numeric protection devices are capable of providing complete protection with added functions like control and monitoring. Numerical protection devices offer several advantages in terms of protection, reliability, and trouble shooting and fault information. Numerical protection devices are available for generation, transmission and distribution systems. The following sections cover relay hardware, relay software, multiple protection characteristics, adaptive protection characteristics, data storage, instrumentation feature, self-check feature, communication capability, additional functions, size and cost-effectiveness.

When would you carry out the calibration procedures for the experiment?

Calibration procedures should be carried out at the beginning of the experiment to ensure accuracy and reliability of the measurements. Additionally, calibration may need to be performed periodically throughout the experiment to account for any changes or drift in the equipment's accuracy.
