POTENTIAL (VOLTAGE) TRANSFORMERS

Do you require a POTENTIAL TRANSFORMER?

Potential transformers (also called "voltage transformers") are used in electrical measuring instruments & electrical protection devices.

SES can supply:

SINGLE PHASE POTENTIAL TRANSFORMERS
THREE PHASE POTENTIAL TRANSFORMERS
FAST TURNAROUND - OFTEN WITHIN DAYS

Advantages of SES POTENTIAL TRANSFORMERS:

Fast turnaround of custom potential transformers - often within days
Optional Electro-static screen between primary & secondary windings
Robust construction
Choice of mounting brackets
Your choice of voltages
Terminal blocks or flying leads
Tough Varnish Coating - either clear or black.
Available in a wide power range - from 10VA to 500 KVA
Insulation classes up to class H - 180Â°C
Australian Standard AS1243 - 1982 compliant

SES has designed & built many POTENTIAL TRANSFORMERS over the past 30 years.

A typical THREE PHASE POTENTIAL TRANSFORMER may be specified as follows:

Specification : Three Phase Potential T/F 415v 50-60Hz / 110v @ 3VA/Ph Burden (4-wire STAR) (4-wire STAR)

Standard : Designed to comply with AS 1243-1982: "VOLTAGE TRANSFORMERS FOR MEASUREMENT AND PROTECTION"

Construction : Open type chassis mountable, double-wound voltage transformer, constructed using high efficiency grain-oriented E-I laminated core for protection application. Primary & secondary terminated to terminal blocks, & input & output star points earthed.

Burden: 3VA / phase

Ratio Error: < 0.5%

Temperature Class : Materials rated at 120 Â°C minimum.

Class of Accuracy: 1.0 P (1%)

Rated over-voltage factor: Fv = 1.9 (designed to operate at 1.9 times primary voltage)

Overall Dimensions : H x W x D = 150 x 150 x 60mm

Weight : 5 Kg

This is just one example of a typical three phase POTENTIAL TRANSFORMER that SES has made. Contact us to discuss your POTENTIAL TRANSFORMER requirements.
