Energy Laboratory
The laboratory has the responsibility of maintenance and dissemination of the unit of
Electrical energy – the kWh.
Energy measurements offered
- Active energy (kWh)
- Reactive energy (kVAhr)
- Maximum demand (VA)
- Power factor
This laboratory is equipped with the following standards.
- Universal meter test bench in conjunction with an electronic substandard meter (EPZ 301) of class 0.05.
- An automatic Portable test system incorporated with TPZ 303 standard meter whose class is 0.02.
With the above-mentioned standards the laboratory is fully capable of offering calibration of both Electromechanical and Electronic (static) energy meters in the laboratory and on-site.
These calibration services are offered to all interested parties. Transformer laboratory
This laboratory is entirely utilized for calibration of both current and voltage instrument transformers. It is equipped with a transformer testing set, which incorporates the following:
Standard current transformer with rate d primary currents from 5A to 3 000A.
Standard voltage transform (unearthed) with rated primary voltages from 5kV to 40kV.
Standard voltage transformer (earthed) with rated primary voltages from 120V to 240 V; 3 kV to 40kV.
Standard burdens for both current and voltage transformers with test point (percentage) magnitude error and angle error displays
Equipment Calibrated in the Lab.
