Description

In this presentation you will learn about "Buck Boost" transformers.

1 Acme Electric Transformer Seminar

2 “BUCK-BOOST” APPLICATIONS Transformer Seminar

3 What are BUCK-BOOST TRANSFORMERS? BUCK-BOOST TRANSFORMERS START OUT AS ISOLATION TRANSFORMERS WITH OUTPUTS FROM 12 TO 48 VOLTS, WHICH GET FIELD CONNECTED AS “AUTO” TRANSFORMERS TO INCREASE OR DECREASE VOLTAGE WITHIN A RANGE OF 5 TO 20 PERCENT. (ie, 208 T0 230 V) THEY DO NOT PROVIDE ISOLATION FROM THE SUPPLY BECAUSE THEY ARE “AUTO” CONNECTED DURING INSTALLATION!

4 PRIMARY SECONDARY AUTOISOLATION “Isolation” vs. “Auto”

5 BASIC PRINCIPLE CURRENT WILL FOLLOW PATH OF LEAST RESISTANCE

6 PRIMARY & SECONDARY have the same CAPACITY

7 BOOSTING CONNECTION COIL VOLTAGES ADD

8 AUTO CONNECTION INCREASES KVA CAPACITY

9 DATA needed to SELECT BUCK-BOOST TRANSFORMER 1. SYSTEM PHASE 2. SYSTEM FREQUENCY 3. LINE VOLTAGE 4. LOAD VOLTAGE 5. LOAD KVA, AMPS, OR HORSEPOWER (Available line voltage should be measured whenever possible)

10 SELECTION EXAMPLE #1 1. 1-PHASE 2. 60 HZ 3. LINE - 189 VOLTS 4. LOAD - 208 VOLTS 5. LOAD - 4 KVA

11 1-PHASE GROUP I CHART REFER TO 1-PHASE GROUP I SELECTION CHART IN SECTION VII OF CATALOG ATD-01.

13 SELECTION EXAMPLE # 2 1. 1 - PHASE 2. 60 HZ 3. LINE - 208 VOLTS 4. LOAD - 240 VOLTS 5. LOAD - 60 AMPS

14 1-PHASE GROUP II CHART REFER TO 1-PHASE GROUP II SELECTION CHART IN SECTION VII OF CATALOG ATD-01.

16 SELECTION EXAMPLE # 3 1. 1 - PHASE 2. 60 HZ 3. LINE - 240 VOLTS 4. LOAD - 208 VOLTS 5. LOAD - 14 KVA

17 1-PHASE GROUP II CHART REFER TO 1-PHASE GROUP II SELECTION CHART IN SECTION VII OF CATALOG ATD-01.

19 SELECTION EXAMPLE # 4 1. 3 - PHASE 2. 60 HZ 3. LINE - 208 VOLTS 4. LOAD - 230 VOLTS 5. LOAD - 80 KVA

20 3-PHASE GROUP I CHART REFER TO 3-PHASE GROUP I SELECTION CHART IN SECTION VII OF CATALOG ATD-01.

23 TYPICAL APPLICATIONS for BUCK-BOOST TRANSFORMERS 1. AIR CONDITIONERS 2. AC MOTORS 3. PUMPS 4. TANNING BEDS (No. 1 application) 5. CONTROL CIRCUITS

24 GENERAL APPLICATION COMPARISON STANDARD ISOLATION TRANSFORMER Handle large increases or decreases in voltage Provide electrical isolation and shielding if required BUCK-BOOST TRANSFORMERS Handle small increases or decreases in voltage (+/- 5 to 20%) Do not provide electrical isolation (because they get “auto” connected)

25 Effects of LOW VOLTAGE on MOTOR OPERATION VOLTAGE CURRENT TEMPERATURE - 5 % + 5 % + 11 % - 10 % + 11 % + 23 % - 15 % + 17 % + 38 %

26 • DETERIORATE INSULATION • NUISANCE TRIPPING OF BREAKERS • INSUFFICIENT MOTOR TORQUE • WASTED ENERGY AND MONEY Effects of LOW VOLTAGE on MOTOR OPERATION

27 Effects of LOW VOLTAGE on MOTOR TORQUE % RATED VOLTS % RATED TORQUE 100% 100% 90% 81% 80% 64%

28 Causes of VOLTAGE MISMATCH • SERVICE VOLTAGE CHANGED AFTER EQUIPMENT INSTALLED • VOLTAGE DROP IN POWER LINE • ERRORS IN ORDERING EQUIPMENT • UTILITY CUTBACK IN SOURCE VOLTAGE

29 GENERAL SIZE COMPARISON STANDARD ISOLATION TRANSFORMER • 16”H X 14”W X 11”D 125 LBS • 1O KVA RATING BUCK-BOOST TRANSFORMER • 10”H X 6”W X 5”D 24 LBS • 1 KVA RATING

30 ACME BUCK-BOOST FEATURES • UL LISTED/CSA CERTIFIED • UL 3R ENCLOSURES • ALLOWABLE UNDER NEC • EPOXY ENCAPSULATED • (EXCEPT 50, 100, 150 VA) • BROAD RANGE OF VOLTAGES • TEN YEAR WARRANTY
