CLIAMS:We claim:
1. A method for on-site monitoring of performance of energy devices, the method comprising:
measuring, by a testing apparatus, a value associated with one or more energy parameters of one or more energy devices in real time;
comparing, by the testing apparatus, the measured value of the one or more energy devices with a predefined set of tolerance values corresponding to the one or more energy parameters of the one or more energy devices; and
indicating, by the testing apparatus, a result of the comparison on a display unit associated with the testing apparatus for on-site monitoring performance of the one or more energy devices.

2. The method as claimed in claim 1 further comprising:
aggregating one or more values associated with the one or more energy parameters of the one or more energy devices in real time; and
comparing the aggregated one or more values with a predefined tolerance value corresponding to the one or more energy parameters of the one or more energy devices for determining error in performance of the one or more energy devices.

3. The method as claimed in claim 2 further comprising:
detecting connection of the one or more energy devices to one or more power switches based on at least one of the result of the comparison and the error in performance of the one or more energy devices; and
swapping the connection between the one or more energy devices to the corresponding one or more power switches.

4. The method as claimed in claim 1 further comprising providing by the testing apparatus, an alert based on the result of the comparison.

5. The method as claimed in claim 1 further comprising providing by the testing apparatus, a recommendation for rectifying the one or more energy devices for on-site monitoring of the one or more energy devices.
6. A testing apparatus for on-site monitoring of performance of energy devices comprising:
a processor;
a memory communicatively coupled to the processor, wherein the memory stores processor-executable instructions, which, on execution, cause the processor to:
measure a value associated with one or more energy parameters of one or more energy devices in real time;
compare the measured value of the one or more energy devices with a predefined set of tolerance values corresponding to the one or more energy parameters of the one or more energy devices; and
indicate a result of the comparison on a display unit associated with the testing apparatus for on-site monitoring performance of the one or more energy devices.

7. The testing apparatus as claimed in claim 6 further comprising one or more communication interfaces to connect to each of the one or more energy devices. .

8. The testing apparatus as claimed in claim 6, wherein the processor is further configured to:
aggregate one or more values associated with the one or more energy parameters of the one or more energy devices in real time; and
compare the aggregated one or more values with a predefined tolerance value corresponding to the one or more energy parameters of the one or more energy devices for determining error in performance of the one or more energy devices.

9. The testing apparatus as claimed in claim 8, wherein the processor is further configured to:
detect connection of the one or more energy devices to one or more power switches based on at least one of the result of the comparison and the error in performance of the one or more energy devices; and
swap the connection between the one or more energy devices to the corresponding one or more power switches.
10. The testing apparatus as claimed in claim 6, wherein the processor is further configured to provide an alert based on the result of the comparison.

11. The testing apparatus as claimed in claim 6, wherein the processor is further configured to provide a recommendation for rectifying the one or more energy devices for on-site monitoring of the one or more energy devices.
12. The testing apparatus as claimed in claim 6, wherein the one or more energy devices is selected from at least one of sensors, meters, and electrical appliances.
13. A non-transitory computer readable medium including instructions stored thereon that when processed by a processor cause a testing apparatus to perform acts of:
measuring a value associated with one or more energy parameters of one or more energy devices in real time;
comparing the measured value of the one or more energy devices with a predefined set of tolerance values corresponding to the one or more energy parameters of the one or more energy devices; and
indicating a result of the comparison on a display unit associated with the testing apparatus for on-site monitoring performance of the one or more energy devices.
