Every Thai Trafo distribution
transformer was
produced under strict supervision of ISO 9001:2000 quality
management system. Such process starts
with an inspection
over every material through
engineering requirements, an in-process inspection
by the production personnel, a reinspection
by QC
officials in prevention
of any nonconforming
product, and a
final inspection
to ensure
correspondence with customer requirement. Every
transformer has to undergo following measurements
and tests prior to delivery (Routine Test).
Measurement of Winding Resistance Measurement
of Insulation Resistance Measurement
of No-Load Loss and Current Measurement
of Load Loss and Short-Circuit Impedance
Measurement of Voltage Ratio and Check of
Phase Displacement Separated
Source Voltage Withstand Test Induced
Over Voltage Withstand Test Transformer
Oil Dielectric Strength Test Oil
Leakage Test
The measurement and test criteria
can comply with every standard such as ANSI,IEC,BS,DIN,JIS,TIS,or
any standard demanded by customer. Additionally,
Thai Trafo also provide devices for type tests on
any
new-designed transformer or any special test demanded
by customer as :
Lightning
Impulse Voltage and Switching
Impulse Voltage Withstand
Test Temperature
Rise Test Partial
Discharge Test Measurement
on Capacitance and
Power Factor of Transformer
