By measuring power using power analyzers at the main panel, you can get information on the general consumption of your facility and compare the energy consumed by the installation with that recorded by the meter.
Monitoring and recording energy and power data lets you ensure that the contracted power corresponds to the actual consumption of your facility. It is common for facilities to have more power contracted than they really need, which translates into higher monthly electric bills.
By installing power analyzers, you can determine the exact amount of power your facility needs and adjust the contracted power accordingly to avoid paying too much.
Power analyzers are also essential to anticipating potential surcharges due to reactive power consumption, since they measure the power factor in real time, indicating whether the facility requires compensation using a capacitor bank, and again helping you avoid paying too much on your monthly bill.
