Coil Analyzers & Power Supplies
-
Coil analyzers and power supply units are portable and lightweight devices intended for use in harsh switchyard and industrial environments. The typical application is switchgear and circuit breaker testing when substation battery is not connected or available. An advantage over substation battery is enabled testing in under-voltage and over-voltage conditions. Furthermore, the stable voltage outputs with a very low ripple (<0,5%) enable an analysis of the coil and motor current graphs recorded with circuit breaker analyzers from different vendors.SAT40AD, POB30AD, and POB40AD are unique devices in the market due to their dual purpose:Power supply for coils and spring-charging motorsTesting circuit breaker’s coils, motor, and auxiliary circuitAll DV Power coil analyzers and power supply units have four separate outputs for opening and closing coils.SAT40AD has two powerful motor outputs (AC and DC) which can withstand up to 40 A inrush current.POB30AD and POB40AD have DC motor output rated up to 30 A and 40 A respectively. With the use of motor outputs, POB and SAT can also be used as a power source or a temporary battery charger.SAT40A II series instruments can be controlled via PC. The DV-Win application software is used to control both SAT and CAT (Circuit Breaker Analyzers & Timers) devices at the same time, making a unique test system for switchgear and circuit breaker testing.

Transformer Ratio Meters
Handheld Turns Ratio & Winding Resistance Tester TWR-H
-
TWR-H is a handheld, battery operated, fully automatic test set specially designed for turns ratio, phase shift, excitation current and winding resistance measurements of transformers. It can also perform demagnetization of these transformers. Transformer turns ratio is determined by applying AC voltage across high voltage winding, accurately measuring AC voltage across the corresponding unloaded transformer winding, and then displaying the ratio of these voltages. User can enter a transformer’s nameplate voltages, so that turns ratio deviation can be calculated. This feature eliminates any error otherwise caused by an operator’s manual calculation. TWR-H compares measured turns ratio with the nameplate ratio and prints out the % of error for each test. Transformer winding resistance is determined by injecting DC current through a winding, accurately measuring DC voltage across the winding, and then calculating resistance as the ratio of voltage and current. The device generates true DC ripple-free currents. Both the injection of the current and the discharge of energy from transformer magnetic circuit are automatically regulated.

Fivestar HV Testing Equipment Co., Ltd.
FSHV offers three different types of AC voltage test systems, the conventional type is AC test transformer design, mainly for testing objects of medium & low capacitance products, particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (like inductive voltage transformers). Another is AC resonant test systems, according to series resonance circuit XL=XC (2πfL=1/2πfC), by setting F frequency of power supply or L inductance of reactor, generate a pure sinusoidal waveform of the test voltage, and the required input power is only 1/Q. Variable frequency type operates in a frequency range from 20Hz to 300Hz, ideal for field commissioning test of power cables and GIS/GIL. Variable inductance type outputs continuous AC voltage of power frequency (50/60Hz), mainly for factory testing of high and ultra-high voltage cables, power transformers, GIS, etc.
