ECSPD
This product was developed to eliminate electric disasters caused by the aging of existing electric facilities, the expansion of use of electric equipment, the increase in electric shocks in streetlights, and the increased surge damage.
Frequency compensation according to frequency modulation prevents electric shock accidents and shields external surges by shielding and reducing leakage current without external interference.
Development background
Increased electric shock and lightning damage
It was developed to reduce electrical disasters that can occur in various general electrical and industrial electrical environments.
Technology principle
ECSPD technology principles guide
It is possible to prevent electric shock accidents by shidlding, absorbing and reducing leakage current without external interference. In addition, it is possible to shield lighting surges.
Waveform improvement by detecting abnormal signs of voltage and current and controlling the frequency compensation
ECSPD principle
ECSPD compensates the frequency by using “waveform (voltage, current) abnormality detection and frequency compensation control device” that utilizes a wavelength band based on the equipotential phenomenon between each phase (single-phase, 3-phase) to change the frequency to a constant amplitude without external interference. It is a principle that the electric power line is arranged electronically so that there is no potential difference, that is, “zero potential” so that no leakage current flows. This is a principle that helps prevent electric shock accidents by shielding, absorbing, and reducing leakage current.
By compensating the frequency with “Detected abnormal condition (voltage, current) and frequency compensation control device”, it is possible to prevent electric shock accident by shielding, absorbing and reducing leakage current without external interference.

| Name | Multifunction grounding leakage current shielding device |
| Model name | • GD-2000 |
| Role / Reason | • Ground fault current shielding. |
| • Acts as a ground distributor. | |
| • Designed to connect FG-E1 and EPG-E2 to utilize 100% of ECSPD functions. | |
| Precaution | • E1: Connect E1 to the load ground. |
| • E2: Connect E2 to the load. | |
| -> If there are many sub-ground wires, a sub-ground wire can be connected by additionally installing a ground divider. | |
| ※ E1, E2 can be connected according to the capacity of the ground wire. | |
| Thickness of ground wire | • Ground wire thickness = circuit breaker (rated current) capacity × 0.0496 |
| Ex) 50A of breaker capacity is 50 × 0.0496 = 2.48 (ie 4SQ), | |
| Breaker capacity 100A is 100 × 0.0496 = 4.96 (ie 6SQ), | |
| The breaker capacity 250A is 250 × 0.0496 = 12.4 (ie 16SQ). | |
| • Use a grounding wire with a size one step larger than that calculated for safety reasons. | |
| • The ground wire of appropriate thickness should be selected in consideration of the protection level and function of the installation site. | |
| • Comply with electrical equipment technical standards or extension regulations. |
