Overview
The energy auto-calibration system is a new generation, high
precision, energy meter calibration equipment. It uses the
advanced technology and components available in update
technology to overcome traditional low efficiency, heat and
reliability problem to increase the work reliability and better
load. The test bench can be used to test the single or three
phase energy meters, and it follows the national standard
and regulation as "IEC60736 : 1982" and "IEC62053" to develop
and design.
The test bench is using the aluminum compound configuration
to form with the digital controlled signal source with PWM
amplifier, standard precision instrument, error system and
auto-testing software. The bench can do the warm up test,
starting test, no load test (creep test), error test (accuracy
test), dial test, tests of the influence quantities and test of
repeatability of the measurements. Moreover, it also has the
auto-search black marker function which can precisely locate
the black marker during the no load test and starting test.
The bench is using the PWM to amplify voltage / current
output with high efficiency at > 85%, and lower heat.
Therefore, it can check the malfunction checking, preset,
alarm, and protection.
The signal source is using the newest digital controlled sine
wave technology for frequency, amplitude and phase adjust.
The bench is using comparison technology to test the error
of energy meters; and the different constant energy meter
can be tested at one time. It is using the error processor
system to calculate the error of each energy meter by the
sub - error system which can be connected by the internal
RS-485.
The energy meter hanging rack is made by Aluminum
compound, the whole device configuration is a reasonable
design and nice outfit. The bench can be installed scanning
head, which can offer 3 ranges adjustment, and it can sample
the signal of round-style energy meter and digital LED
energy meter.
The test bench is using the testing software complied with
WINDOWS98 / 2000 / XP which can auto-testing different
energy meters. The software includes Database Management
System to realize the data from energy meter for gathering
statistics, category search and management.
The test bench of operating conditions :
- Ambient temperature 10oC to 50oC for operation and from -10oC to +65oC for storage.
- Relative humidity up to 85%.
- Power supply : 220V / 240V +15% for single phase supply. 3*220V / 380V(Y) +15% for three phase supply.
- Frequency 50Hz +10%.
